UNIT 1 REVIEW (PLATE TECTONICS, ROCK CYCLE, GEO TIME SCALE)

Front

What is subduction?

Back

Subduction is when two tectonic plates converge, and one plate slides under the other due to its higher density.

Front

Give an example of a sedimentary rock.

Back

An example of a sedimentary rock is sandstone.

Front

What do paleontologists study?

Back

Paleontologists study fossils.

Front

What is the layer of the Earth located under the crust?

Back

The layer of the Earth under the crust is called the mantle.

Front

What are fossils?

Back

Fossils are evidence of past life.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through various geological processes.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is the core of the Earth?

Back

The core is the innermost layer of the Earth, composed mainly of iron and nickel.

Front

What is a trench in geology?

Back

A trench is a deep, narrow depression in the ocean floor, often formed by subduction.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from cooled magma or lava, while sedimentary rocks form from the accumulation of sediments.
