Review #1: Geology and Biomes
Name: _________________________
Many dynamic processes, both internally and external, have shaped our Earth since its inception. These processes
can act to renew and reestablish life, or destroy it.
a) Identify and describe a type of chemical and physical weathering process that helps shape the planet.
b) i. Discuss what type of tectonic interactions could lead to the formation of an earthquake.
ii. What is the difference in amplitude measured between two earthquakes of 7.0 and 4.0 on the Richter
Scale.
iii. Identify TWO environmental or economic impacts earthquakes can have.
c) What geologic activity most likely occurred to form the Mariana’s Trench?
d) Discuss how tsunamis form and what natural barriers in the ecosystem help protect humans living in
coastal areas.
Differences in average annual precipitation and temperature largely determine the location and lead to the
formation of our biomes. Desert biomes typically experience larger evaporation than precipitation. Annual
precipitation in desert ecosystems is low and often scattered unevenly during the year.
a) Describe how the rain shadow effect has played a role in forming some major desert ecosystems in the
world.
b) Explain why desert ecosystems take a long time to recover from any environmental disturbance.
c) Identify some adaptations a plant and animal may utilize to be successful in the desert ecosystem.
d) Discuss TWO anthropogenic factors that lead to an increasing distribution of deserts globally.
