Earth Science 1st Semester Exam Review

Which description best represents heat flow and movement in Earth's mantle?

• When magma is heated, it becomes more dense and sinks. When magma is cooled, it becomes less dense and rises.

• When magma is heated, it becomes less dense and sinks. When magma is cooled, it becomes more dense and rises.

• When magma is heated, it becomes more dense and rises. When magma is cooled, it becomes less dense and sinks.

• When magma is heated, it becomes less dense and rises. When magma is cooled, it becomes more dense and sinks.

The list describes one of Earth's layers:

• Composed of iron and nickle.
• Contains both liquid and solid parts.
• Extremely hot.

The list is describing:

• the core because strong pressure and temperature create both liquid and solid parts.

• the core because weak pressure and temperature create a hot environment.

• the mantle because strong pressure and temperature create a hot environment.

• the mantle because weak pressure and temperature create both liquid and solid parts.

The distance from the Earth's surface to the center of the Earth is

• 60 km

• 600 km

• 6,000 km

• 60,000 km

The diagram shows the layers of the Earth.

Which statement best describes layer 1 and layer 2?

• Layer 1 is the inner core and is solid. Layer 2 is the outer core and is liquid.

• Layer 1 is the outer core and is liquid. Layer 2 is the inner core and is solid.

• Layer 1 is the inner core and is not hot. Layer 2 is the outer core and is very hot.

• Layer 1 is the outer core and is not dense. Layer 2 is the inner core and is very dense.

Which of the following models shows the correct representation of the two layers closest to the center of the Earth?

• A

• B

• C

• D

What layer of Earth contains the plates that cause earthquakes and volcanic eruptions?

• the inner core

• the atmosphere

• the outer core

• the lithosphere

Magma rises to become new oceanic crust where

• one plate splits into two distinct plates.

• one plate grinds against another plate.

• two plates separate and move apart from one another.

• two plates meet and collide with one another.

New ocean crust continuously forms

• at mid-ocean ridges.

• where sediment is thickest.

• near deep-ocean trenches.

• at areas of low tide.

Crust is neither formed nor destroyed along which type of boundary?

• convergent

• transform

• collisional

• subduction
