Earth's Layers and Plate Tectonics

The layer of Earth that is found directly below the lithosphere is called the -

• asthenosphere.
• inner core.
• outer core.
• crust.

Which layer of Earth is broken up into giant moving plates?

• Asthenosphere
• Lithosphere
• Inner core
• Outer core

Earth’s crust would be best modeled by using a material that is -

• liquid and hot.
• dense and smooth.
• soft and flexible.
• thin and solid.

The materials available to make a model of Earth are shown. To make the most accurate model, which of the materials would best represent the asthenosphere?

• Modeling clay
• Ping pong ball
• Ball bearing
• Water

What are usually common at transform boundaries?

• volcanoes
• earthquakes
• rivers
• deserts

What travels from the mantle in order to form new crust?

• magma
• outer core
• convection currents
• asthenosphere

What type of boundary interaction is this?

• oceanic-continental

• continental-continental

• oceanic-oceanic

• divergent

Order the layers of the Earth from the most dense to the least

• crust, mantle, outer core, inner core
• inner core, outer core, mantle, crust
• crust, mantle, inner core, outer core
• inner core, outer core, crust, mantle

What is a difference between oceanic & continental crust?

• Continental is thicker
• Oceanic is thicker
• Continental is made of basalt
• Oceanic is made of granite

State of matter the rocks that are in the mantle:

• Solid
• Liquid
• Gas
• Semisolid
