What Is Relief Class 9 Geography
Hint: Relief features refer to the landscapes in India. They are the mountains, valleys etc. The relief features of a country display the topography of that area. The Himalayas in India, which are one of the most important physical features, are geologically very young and neatly and structurally folded mountains.
The Fourth Order Of Relief
The fourth order is made up of smaller features, “landscape” scale features. Nearly ubiquitous at this scale, if spatially varying in density, are the impact features: craters at every size, level of modification, and degree of superposition. There are pristine, bowl-shaped craters with sharp rims, such as Zunil Crater and craters so new they still have debris blown around them, such as this one in Arabia Terra that formed between April 2001 and December 2003 ). There are craters perched on top of pedestals or ramparts of their own consolidated ejecta blankets, which then become elevated above the landscape as erosion removes materials around them, as seen on the frozen plains of Acidalia Planitia . There are craters with erosion-softened edges and floors nearly flat with lava, sedimentary, glacial, snow, or æolian fill, such as this glaciated pair of craters on the east side of Hellas Planitia , the snow-covered Udzha Crater near the North Polar Cap , Victoria Crater with its dunes , and the seemingly sedimentary fill in Schiaparelli Crater since etched out by the wind . Many craters are completely buried by newer surfaces, as revealed by these subsurface radar soundings by the Mars Express MARSIS sensor.
The fourth order landscapes include such fluvial features as deltas , valles that look like fluvial networks , and gullies in the walls of south polar pits that resemble sapping outflow features on Devon Island in the Canadian Arctic ).
Meaning Of Relief In Geography
Ingeography, Relief means the difference between highest and the lowest points ofelevation or height. It refers to topography and can be shown on maps usingContour Lines.
The difference in elevationbetween nearby points, usually within a given area, is called Local Relief.

Why Is Terrain Relative Relief Important
On land, the context of a feature within the landform and its surroundings has implication for soil characterisation and associated geomorphological processes. Terrain relative relief is scale-dependent, being derived from elevation of the terrain feature at a finer scale than the scale at which it is reported. In digital soils mapping and modelling, relative elevation or relief is a secondary terrain derivative metric diagnostic of soil processes associated with water running through the landscape .
Terrain relative relief is important in the intertidal and subtidal environment for both biodiversity and underlying geomorphology. Specific faunal groups may require specific thresholds, for example variations in vertical relief was the best abiotic surrogate to explain abundance, diversity and community composition of temperate rocky reef biodiversity. Microrelief was a significant factor for seagrass annual colonisation, that is, the seagrass in the hollows had longer shoots and greater above ground biomass.
Savanna Or Tropical Grassland
The margin of the Savannahcoincides with the rain forest belt where dry conditions begin. In such areas,there is often a mosaic of forest savanna. Further away from the forest, as thedry season becomes more pronounced and more prolonged, the Savannah woodlandthins out, and trees that are more drought resistant are found. Generally, the prevailing vegetation cover is grassinterspersed with trees . Inthe zone of lower rainfall the huge baobab tree illustrates storage of waterwhile ‘umbrella’ trees show adaptation to dry wind. Acacias, some producinggum, are a feature of the drier Sudan savanna. The Savanna extends with similardifferences in character over the Lake plateau across the Zambezi to theDrakensberg and dries towards the Kalahari in the thorny scrubs of theBushveld. Major crops produced in the Savanna: millet, sorghum, peanuts, andcotton.
6.Temperate Grassland or Veld
This is found inthe veld areas of South Africa. Characterized by short grass and plants adaptedto a brief growing season but there are considerable differences due toaltitude. It is by no means adapted everywhere to cultivation, but maize,tobacco and temperate cereals are grown

What Are The Relief Features
Answer: The characteristics that are related to the landscape of specific areas are known as relief features. In geography, the sense of relief implies the highest and lowest elevation points in a particular region. Mountains & ridges and valleys are elevated points of elevation and are examples of low lying areas.
Examples Of Topography In Maps
Theres no world authority in topographic mapping. Instead, each country sets its own standards and priorities. Most often the case, each mapping agency designs its topographic maps with a specific goal in mind.
For example, constructing a new highway might drive a topographic map to feature woodland cover, soil types, or rock classification along the route. Over time, topographic map series often get periodic updates. But the truth is, they can be complex and take years to create.
In the United States, the first USGS topographic map was surveyed in 1892. Since then, map revisions have continued for over 125+ years. The USGS produce topo maps at 1:250,000, 1:100,000, 1:63,360 and 1:24,000. The most common is the 7.5 minute quadrangle series where one inch in the map represents 24,000 inches on the ground.
Another example of a topographic map is the USGS Tapestry of Time and Terrain. In this colorful map, it overlays topography with underlying rock formations. This helps unravel the geologic history of the continent, such as mountain building events.

Disadvantages Of Debt Relief
The possible drawbacks of debt relief are that it could encourage imprudent and reckless behavior by historically fiscally irresponsible parties. Some who are relieved of their debt may embark on borrowing sprees in the expectation that their creditors will eventually bail them out.
Other drawbacks include prolonging the payoff of debt due to consolidation, whereby the interest rate is lowered but the term is lengthened. In general, debt-relief measures can also negatively impact your credit score, so you should use them sparingly.

Pressuresystems Winds And Itcz
Located on aboutLatitude 30o North and South of the Equator are Sub-tropical HighPressure Belts that dictate surface wind patterns and also influence rainfalland temperature regimes on the continent. The Subtropical High Pressure Systemson both sides of the Equator generate two wind systems that converge on theequator in a zone termed Inter-Tropical Converge Zone . From the north,Subtropical High Pressure Belt zone blows the Northeast Trade Winds . The Harmattan is dry and cool and blows over Sub-SaharanAfrica from about November to April. From the south Sub-tropical High Pressurebelt zone blows the Southwest Trade Winds . The Monsoonwinds are moist and bring rainfall to the coasts of West Africa. The Africancontinent does not extend much beyond 35oof latitude from the equator. The implication is that the rangeof climatic conditions is limited and that the general direction of windmovement is towards the equator . The ITCZ shifts with the seasonalmovement of the sun across the tropics:
· In June: the northern Summer season, the ITCZ is located at about13 degrees of latitude in North Africa at the southern boundary of the Sahara
· In December: the Northern winter season, the ITCZ moves southwardalong the West African Coast and to the northern and eastern margins of theZaire basin and continues to Madagascar

What Is Relief Rainfall
Relief rainfall, also known as orographic rainfall, occurs in areas where land increases in height. It is very common on the west coast of the United Kingdom due to the prevailing weather coming from that direction.
Relief rainfall is formed when the air cools as it rises over relief features in the landscape such as hills or mountains. As the air rises, it cools, condenses and forms rain.
In the UK prevailing winds from the west lead to air rising over upland areas such as the Pennines. As the result of this rainfall totals of over 1,600 mm per year occur in the west of the UK. The downwind or leeward slope receives a small amount of rainfall in comparison.

What Is Debt Relief
Debt relief is the reorganization of debt in any shape or form so as to provide the indebted party with a measure of respite, either fully or partially. Debt relief can take a number of forms: reducing the outstanding principal amount , lowering the interest rate on loans due, or extending the term of the loan, among others.
Creditors may only be willing to consider debt-relief measures when the repercussions of debt default by the indebted party or parties are perceived as being so severe that debt mitigation is a better alternative. Debt relief may be extended to any highly indebted party, from individuals and small businesses to large companies, municipalities, and even sovereign nations.

Queensland Intertidal And Subtidal Ecosystem Classification Scheme
The terrain relative relief categories of seascape and habitat in the Intertidal and Subtidal Ecosystem Classification Scheme reflect Speights landform pattern and element of the Australian Soil and Land Survey Field Handbook. Being relative, the categories will reflect the range of available elevations of morphological features within a sampled area . A range of features of various elevations within a sampled area will need to be categorised into higher differences in elevation versus lower differences in elevation.
Topography Applications And Uses
Topographic maps show how rivers flow, how high mountains rise and how steep valleys descend. They lay out the land such as in these examples:
- Engineers use topographic maps to plan a road, construct a cell tower or plan a hydroelectric dam.
- Geologists use topography to understand tectonic activity, landforms and where to dig a mine.
- Hikers use topographic maps to find trails and steepness of slope to plan their ascent.
- Astronomers study the topography outside Earth like on the moon, Mars or an asteroid.
- Climate scientists tie topography into climate models to recognize air and water flow.
As landscapes evolve and technology advances, topographers face an uphill battle for accuracy and completeness.

Plant and animallife distribution and the different climatic/soil belts are closely related.Although some parts of the continent retain their natural/virgin flora andfauna, increasing population and human activities seem to be endangering theseplaces. The Following types of vegetation types identified:
1.Tropical Rain forest:
This vegetationdevelops in low land areas with year-round precipitation. It extends throughoutthe Congo basin and along the West coast of Africa with its widest inSierra Leone. It is also found in a narrow belt along the Southeastern coast southfrom the equator. Madagascar has a unique rain forest with special species offauna and flora not available on the main land. Generally, a heavy canopy offoliage with lianes and epiphytes characterizes the rain forest. It occurs inregions where high temperatures are combined with heavy precipitation.
This vegetationis poorly represented in Africa. It is only found on the lower slopes of theEthiopian highlands and elsewhere on the highlands of considerable elevation andrainfall
This vegetationis found at the inter-tidal flats of the coastlines within the tropics.
