Semester Exam Review 1

Why do regions in high latitude receive less sun than those at low latitudes? 

• more light is reflected at high latitudes than at the equator
• the sun's rays strike earth's surface less directly at high latitudes
• the equator has less distance from the sun than either pole

Which two are responsible for earth's tectonic plate movement?

• Rotation of the earth & trade winds
• weathering & erosion
• convection & gravity 

Which is responsible for the formation of soil?

• weathering and decay of dead organisms 
• ocean currents and trade winds
• tectonic plate movement and sea floor spreading 

Why does soil take longer to form in deserts than in forest? 

• there are no rivers to carry silt in deserts
• there is less organic matter in deserts than forest
• desert plants can withstand higher temperatures

_________boundaries occur when two tectonic plates slide towards each other

• divergent
• convergent
• transform 

Which term describes all living organisms on the earth? 

• Hydrosphere
• Lithosphere
• Biosphere 

Which physical forces impact or cause changes to the earths lithosphere? 

• earths rotation and revolution around the sun
• tectonic plate movement, weathering and erosion
• ocean currents and trade winds 

Which occurs in the hydrosphere? 

• A. the transformation of rock from sedimentary to metamorphic
• B. the circulation of hot and cold oceanic currents
• C. the regulation of the rate at which thermal energy leaves the planet

Which of the following describes how elevation generally influences climate?

• The higher the elevation, the lower the average temperatures
• The lower the elevation, the lower the average temperatures
• . The higher the elevation, the lower the average wind speed
