Parts of the Earth/Plate Tectonics

The relatively thin layer of gases that form Earth's outermost layer is called:

• Biosphere
• Atmosphere
• Energy
• Constructive Force

The Hydrosphere contains all of Earth's ______________

• Water
• Air
• Life
• All of the above

The Outermost layer in the Earth is called

• Mantle
• Crust
• Core
• None of the above

From the outside to the inside, the correct order of the layer of the Earth is

• Core, Mantle, Crust
• Crust, Core, Mantle
• Crust, Mantle, Geosphere
• Crust, Mantle, Core

Earth's crust is broken into large pieces called

• Continents
• Countries
• Tectonic plates
• Oceans

The Crust is divided into Continental and Oceanic Crust

• True
• False

Convection currents in this layer move tectonic plates.Which of Earth's layers does this statement describe?

• inner core
• outer core
• mantle
• crust

Which statement correctly explains how convection causes movement of the crustal plates?

• Crustal plates move when tides are high on one side of Earth and low on the other side.
• Crustal plates move when hot magma rises and more dense, cooler magma sinks.
• Crustal plates move when the moon's gravity pulls on different parts of Earth.
• Crustal plates move when water inside Earth's core changes from liquidto vapor.

Tectonic plates are part of which layer of the Earth?

• Lithosphere
• Asthenosphere
• Mantle
• Outer core

Describe the movement of tectonic plates at a convergent boundary.

• Plates move away from each other
• Plates move towards each other
• Plates slide past each other
