2.3 Weathering and Climate

If the temperature is -10 degrees Celsius, and the precipitation is 25 centimeters, what type of weathering is more dominant?

If the temperature is 15 degrees Celsius, and the precipitation is 75 centimeters, what type of weathering is more dominant?

If the temperature is 3 degrees Celsius and the precipitation is 40 centimeters, what type of weathering is more dominant?

What type of weathering would be more dominant at high temperature and high precipitation?

If the climate is arid and cold, what type of weathering is more dominant?

If the climate is humid and warm, what type of weathering is more dominant?

Which change in the climate of New York State would most likely cause the greatest increase in chemical weathering of local bedrock?

In which type of climate does chemical weathering usually occur most rapidly?

The Grand Canyon is a desert. One third of Earth's land mass is desert. Deserts have low rainfall, sparse vegetation and extensive exposed rocky areas. Not all deserts are in hot climates; Antarctica is a desert. The desert environment effects how weathering changes the landscape. Since much of the desert landscape is bare rock and desert soil has little to hold it in place, water and wind play a much more dominant role in weathering than in other biomes. In contrast, evaporation exceeds precipitation in desert climes, retarding chemical-weathering processes. The most spectacular form of weathering in the desert is caused by the wind. Wind sculpts rock by picking up tiny rock particles and abrading rock surfaces. Is this area humid or arid? ___________________
