What is the subject of geography?
Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. Geography seeks to understand where things are found, why they are there, and how they develop and change over time.
What subjects are studied under physical geography?
Topics include all aspects of terrestrial and extraterrestrial geology, geochemistry, geophysics, mineralogy, petrology, economic geology, hydrology, oceanography, geomorphology, geoarchaeology, and engineering geology.
Who is father of physical geography?

What are the physical characteristics of a desert ecosystem?
The vast majority of the geographic features in the desert include only sand or rocks and gravel. Vegetation, although diverse, is scare. Though there are sand dunes that appear as hills, the lie of the land is flat. A water-rich ecosystem that can be found in the desert is called an oasis.
What are the components of a desert ecosystem?
In general, deserts are made up of a number of abiotic components – including sand, the lack of moisture, and hot temperatures – basically anything that makes up an ecosystem that isn’t alive.
Why are deserts extreme environments?
Deserts are perhaps one of the most difficult places to live. The main characteristic of deserts is that they are extremely dry. Because humans need so much water, surviving in deserts is very difficult. This, in turn, makes it even harder for human life to persist because there is always risk of running out of food.
What are examples of extreme environments?
Examples of extreme environments include the geographical poles, very arid deserts, volcanoes, deep ocean trenches, upper atmosphere, Mount Everest, outer space, and the environments of every planet in the Solar System except the Earth.
What is one disadvantage of living in a desert?
Lack of water, the most evident disadvantage to deserts in general, results from the combined effects of insufficient rainfall and rapid water evaporation by nearby land masses. The rate of rainfall rarely exceeds the rate of evaporation, and it is not uncommon for rain to vaporize even before hitting the ground.
