FAST review Dynamic Earth and Rock Cycle

Front

What are the layers of the Earth from top to bottom?

Back

The layers of the Earth from top to bottom are: outer core, upper mantle, asthenosphere, lithosphere, inner core, lower mantle.

Front

What does the small rubber ball represent in a model of the Earth?

Back

The small rubber ball represents the inner core of the Earth.

Front

What material is used to represent the mantle in a model and why?

Back

Foam is used to represent the mantle because it is thick and squishy but still solid.

Front

How did the Hawaiian Islands form?

Back

The Hawaiian Islands are formed as a result of the Pacific Plate moving over a stationary hot spot.

Front

What supports the continental drift hypothesis?

Back

The presence of similar rock formations found on widely separated continents supports the continental drift hypothesis.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, allowing for tectonic plate movement.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid and also made of iron and nickel.

Front

What is a hot spot in geology?

Back

A hot spot is a location where magma from deep within the mantle rises to the surface, creating volcanic activity.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through processes like weathering, erosion, and metamorphism.
