Define relief. What is the total relief exhibited on Earth's surface? What is the relief within the state where you live?

What will be an ideal response?

Question 2

Consider that the wood blocks represent the crust and the part of each block below the surface of the water represents the root of the mountains that extends downward into the mantle (the water).

Use this analogy to explain how removing wood from the top of Block A explains exposure of metamorphic rocks that are found at the core of mountains.

Question 3

Long, high mountain ranges typically form near ocean-continent convergent plate boundaries. One example of a mountain range near an ocean-continent convergent boundary is the Andes in South America.

What type of stress (compression or tension) probably caused the Andes? What type of faults would you expect to find if you visited the Andes?

Question 4

Mountains stand high compared to nearby plains. Which region, mountains or plains, do you predict will have the thicker crustal root? Please explain.

Answer to Question 1

Relief is the difference in elevation between two locations. The highest point on Earth is Mount Everest at 8850 meters above sea level. The lowest point on Earth is the Mariana trench at 11,040 meters below sea level. The variation in relief exhibited on Earth's surface is 19,890 meters.

Answer to Question 2

Thank you

Answer to Question 3

Thank you

Answer to Question 4

If the mountains are standing up higher, the implication is that the root below them is thicker and less dense such that they stick up higher above the mantle.
