  2. Faulting

  3. Volcanism

  4. Block Mountain Formation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Block mountain formation occurs when large blocks of Earth's crust are uplifted along faults, resulting in steep-sided mountains with relatively flat tops, such as the Grand Tetons in Wyoming.

  2. Mantle Formation

  3. Crust Formation

  4. Atmosphere Formation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Core Formation is the process by which a solid core forms at the center of a planet through the accumulation of heavy elements, such as iron and nickel.

  1. Earthquakes that occur in glaciers

  2. Earthquakes that occur near glaciers

  3. Earthquakes that are caused by glaciers

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Icequakes are earthquakes that occur in glaciers. They are caused by the movement of ice and snow within the glacier.

Multiple choice

What is the principle of stratigraphy?

  1. The law of superposition

  2. The principle of original horizontality

  3. The principle of cross-cutting relationships

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The principle of stratigraphy is based on the law of superposition, the principle of original horizontality, and the principle of cross-cutting relationships. The law of superposition states that in a sequence of sedimentary rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. The principle of original horizontality states that sedimentary rocks are originally deposited in horizontal layers. The principle of cross-cutting relationships states that a younger feature will cross-cut an older feature.
