Earth Science Final Review

Front

What is a rock that is not formed from solidified lava?

Back

Lava is not a rock; it is molten rock that has not yet solidified.

Front

What geological features are associated with the theory of plate tectonics?

Back

Mountain ranges are geological features that prompted the development of the theory of plate tectonics.

Front

Why do massive stars have shorter lifespans than average stars?

Back

Massive stars burn their fuel faster than average stars.

Front

What type of rock is formed from fragments of other rocks?

Back

Sedimentary Rock is formed from fragments of other rocks.

Front

Where does sea floor spreading most likely occur?

Back

Sea floor spreading most likely occurs at divergent plate boundaries (oceanic vs. oceanic).

Front

What is the definition of sedimentary rock?

Back

Sedimentary rock is a type of rock that is formed by the accumulation and compaction of mineral and organic particles.

Front

What is the process of sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is formed at divergent boundaries as tectonic plates move apart.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive slab of solid rock that makes up the Earth's lithosphere and moves over the semi-fluid asthenosphere.
