Question 5

A desert may form along a coastline because a

warm current warms and dries the air.

warm current forces hot air inland.

cold current cools and dries the air.

cold current forces hot air inland.

Question 7

You find evidence of changes in sea level along a coastline. How can you tell if they are the results of glaciers?

Look for evidence of glacial till in the form of moraines, drumlins, kettle lakes, or stratified glacial outwash sediment.

Determine if the sea level changes coincide with the advance of glaciers in the mountains nearest to the coastline.

Determine the timing of the changes in sea level and look for evidence of changes in sea level in other places around the world.

Determine if the area contains evidence of glacial erosion such as U-shaped valleys, striations, erratics, and rock flour.

Question 9

Why is chemical weathering relatively rare in deserts?

Chemical weathering requires much colder temperatures than are seen in deserts

Physical weathering occurs only in hot regions; thus it is more prevalent in deserts

Chemical weathering only occurs in the presence of salt water from the ocean

Chemical weathering most often involves reaction with water, which is rare in deserts

Question 11

climate change

earthquakes

landslides

flooding

Question 19

The Mars rover Curiosity has recently found evidence that there was liquid water on the planet’s surface at some point in its history. Because we have not found any liquid water on the planet today, what does this imply about Mars?

The planet was once covered entirely in liquid water.

A drought must have removed all the water from the surface

The climate was once warm enough that the polar ice caps melted.

The interior of Mars must be made entirely of liquid water.

Explanation / Answer

5) cold current cools and dries the air As air rises, it cools and loses its moisture. As it descends, it warms and picks up moisture, drying out the land.

7) Determine the timing of the changes in sea level and look for evidence of changes in sea level in other places around the world.

9) Chemical weathering most often involves reaction with water, which is rare in desert

11) climate change

15) striations

16) talus

17) increase; increase

18) solar insolation; orientation,  In the 1920s, he theorized that variations in eccentricity, axial tilt, and precession of the Earth's orbit resulted in cyclical variation in the solar radiation reaching the Earth, and that this orbital forcing strongly influenced climatic patterns on Earth.

19) The climate was once warm enough that the polar ice caps melted

20) long-term drought

21) desertification

22) loess
