Techniques Used In Geography
Maps have been the key tool in geography. Cartography, which has been a classical tool in geography, has now received modern approaches through the use of computer-based geographical information systems , geographical analysis, remote sensing, Qualitative and quantitative techniques among many others.
Importance Of Geography And Geology
Geography and geology give us the understanding of the substances on Earth, the structure, history, and the processes acting on our planet. Human beings rely entirely on the resources found on the Earth’s surface and below it. It helps us to understand how to interact and utilize the resources found on our planet as well as how to care for our world, the flora, and the fauna. It also helps humanity to understand natural phenomena such as volcanic eruptions, earthquakes, hurricanes, etc. so that they can protect themselves from any such events in the future.

Difference Between Geography And Geology
The main difference between geography and geology is that geography is mostly dealing with the physical overall shapes of the land. Geology is a science that is interested in how the land got into the shape it did.
Geology is mostly about what the ground is made up of from a natural perspective. What kind of rocks it contains and how those rocks or layers of rocks got there.
Geography is mostly dealing with mapping the extent of landforms, how far rivers are, how long mountain ranges are, how long the coast line is. This is often from the perspective of people or culture.

The ending of the word also is an indication of the differences between geography and geology. _graphy means to draw or record. In other words, ‘to draw the land’ and _ology meaning ‘to find knowledge of the land’
What Does A Geologist Do
Geologists work to understand the history of our planet. The better they can understand Earths history, the better they can foresee how events and processes of the past might influence the future. Here are some examples:
Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. Geologists work to understand these processes well enough to avoid building important structures where they might be damaged. If geologists can prepare maps of areas that have flooded in the past, they can prepare maps of areas that might be flooded in the future. These maps can be used to guide the development of communities and determine where flood protection or flood insurance is needed.
Geologists study Earth materials: People use Earth materials every day. They use oil that is produced from wells, metals that are produced from mines, and water that has been drawn from streams or from underground. Geologists conduct studies that locate rocks that contain important metals, plan the mines that produce them and the methods used to remove the metals from the rocks. They do similar work to locate and produce oil, natural gas, and groundwater.

Main Differences Between Geography And Geology
Towards A New Definition Ofgeography
Geographers examine physical and human features, processes and systems and how they interact with the environment at local, regional, and global scales and assess them using the four concepts of Geographical Thinking:
Spatial Significanceis about where a feature is located, its actual and relative location, and why it is important there i.e. What unique natural and human features are present and how might they interact?
Patterns & Trends: A pattern is a characteristic or feature that repeats over space: within and between places or regions. Low latitudes are warm and wet high latitudes are cold and dry. This is a pattern. Rivers form distinct and predictable drainage patterns depending on the rock and soil of a region. A trend is when a characteristic or feature changes over time, such as the population growth Canada has experienced since colonization. But a trend can also be a change over space for example as you hike uphill, the temperature gradually becomes colder.
Interrelationships: Similar to a relationship between two people, in geography interrelationships are the interactions that occur between and among natural and human geographic features and processes. For example, the type of agricultural crop planted by farmers depends on the soil, precipitation, and temperature of the region. And, where there are mountains and snow, you will find ski resorts.
This ArcGIS StoryMap provides an excellent example of how Geographic Thinking works, in the Canadian Context.

Timescale Of The Earth
The following five timelines show the geologic time scale. The first shows the entire time from the formation of the Earth to the present, but this gives little space for the most recent eon. Therefore, the second timeline shows an expanded view of the most recent eon. In a similar way, the most recent era is expanded in the third timeline, the most recent period is expanded in the fourth timeline, and the most recent epoch is expanded in the fifth timeline.

Connecting With Space And Place
Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earths surface and the human societies spread across it. They also examine how human culture interacts with the natural environment and the way that locations and places can have an impact on people. Geography seeks to understand where things are found, why they are there, and how they develop and change over time. Read More…
Hydrology And Environmental Issues
Geology and geological principles can be applied to various environmental problems such as stream restoration, the restoration of brownfields, and the understanding of the interaction between natural habitat and the geological environment. Groundwater hydrology, or hydrogeology, is used to locate groundwater, which can often provide a ready supply of uncontaminated water and is especially important in arid regions, and to monitor the spread of contaminants in groundwater wells.
Geologists also obtain data through stratigraphy, boreholes, core samples, and ice cores. Ice cores and sediment cores are used for paleoclimate reconstructions, which tell geologists about past and present temperature, precipitation, and sea level across the globe. These datasets are our primary source of information on global climate change outside of instrumental data.

Main Difference Geology Vs Geography
Geology and Geography are two fields that study Earth in a scientific view point. Geology is the study of physical structure and substance of the Earth, their history, and the processes which act on them. Geography is the study of the physical features of the Earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources and political and economic activities. The main difference between geology and geography is that geology studies the structure and formation of earth whereas geography deals with the topography of Earth.

Geological Development Of An Area
The geology of an area changes through time as rock units are deposited and inserted, and deformational processes change their shapes and locations.
Rock units are first emplaced either by deposition onto the surface or intrusion into the overlying rock. Deposition can occur when sediments settle onto the surface of the Earth and later lithify into sedimentary rock, or when as volcanic material such as volcanic ash or lava flows blanket the surface. Igneous intrusions such as batholiths, laccoliths, dikes, and sills, push upwards into the overlying rock, and crystallize as they intrude.
After the initial sequence of rocks has been deposited, the rock units can be deformed and/or metamorphosed. Deformation typically occurs as a result of horizontal shortening, horizontal extension, or side-to-side motion. These structural regimes broadly relate to convergent boundaries, divergent boundaries, and transform boundaries, respectively, between tectonic plates.
What Can I Do With My Geology Degree
Opportunities for interesting and rewarding careers abound for students with degrees in geology. The American Geological Institute reports that there are about 120,000 geoscientists currently working in the United States. Moreover, a survey by the Bureau of Labor Statistics indicates that the number of active geoscientists and hydrogeologists is expected to increase by about 18% by 2018, a pace that exceeds that average for all occupations.
According to the BLS survey, the median annual wages of geoscientists of all types in May 2008 was $79,160 . Median wages are generally higher in the oil and gas industry and for those employed by the Federal Government , whereas jobs in state government agencies generally pay less than the overall average . The National Association of Colleges and Employers reports that average starting salary for college graduates with bachelor’s degrees in geoscience was $40,786 in 2007.
