Plate Tectonics and Rock Cycle Review

What is the lithosphere?

• another name for Earth's crust

• the part of the mantle near the core where it is hottest

• the outer, rigid part of the mantle and the crust combined

• the part of the core that is closest to the mantle where it is coolest

Igneous rocks are classified by __________. Rocks that __________ are called intrusive rocks, and rocks that __________ are called extrusive rocks.

• how fast they cool; cool slowly; cool quickly

• how hot they get; are hotter; are cooler

• how large they are; are larger; are smaller

• how dense they are; are denser; are less dense

What is the pattern of earthquakes and volcanoes across the Earth?

• They are both spread evenly across the Earth.

• Earthquakes occur wherever volcanoes do not.

• Volcanoes are found only on islands, and earthquakes are found only in the middle of continents.

• They are both mostly found in narrow zones around the edges of continents and ocean basins and along island chains.

How is rock formed through physical sedimentation?

• Magma is deposited on the Earth’s surface where it hardens.

• Water dissolves sediment for later crystallization or use by organisms.

• Sediment is moved continuously by the elements, collecting more rock as it moves.

• Rock is broken down by the elements into tiny fragments that are later deposited and compacted together.

A chain of volcanic mountains found on the seafloor is called a __________.

• trench

• fracture zone

• mid-ocean ridge

• continental shelf

The process in which water dissolves sediment for later crystallization or use by organisms is called __________.

• water deposition

• rock reintegration

• aqueous transformation

• chemical sedimentation

Rocks near mid-ocean ridges are __________ rocks further away. This phenomenon is due to a process called __________.

• the same age as; weathering

• a different type from; deposition

• older than; seafloor converging

• younger than; seafloor spreading

What are the two main processes that form metamorphic rock?

• intrusion and extrusion

• mineralization and pressurization

• deformation and recrystallization

• physical and chemical sedimentation

Which of the following statements about oceanic crust recycling is true?

• Scientists no longer believe crust gets recycled.

• Crust is recycled at mid-ocean ridges where two plates crash into each other.

• The old crust in ocean trenches sinks into the mantle where it is destroyed.

• Crust gets hotter as it gets older, floating over newer crust that is then destroyed.

Which of the following is NOT a way that deformation may change a rock?

• Bands of rock bend into wavy shapes.

• Rock crystals become longer and thinner.

• Rock crystals line up parallel to each other to form bands.
