Earth's Layers, Earthquakes, Plate Tectonics

We can dig, drill, and send sensors down to investigate Earth's layers

• True

• False

What kind of rock forms the oceanic crust?

• basalt

• granite

This sublayer includes the crust and upper mantle and is made of rigid, brittle rock plates that move.

• lithosphere

• asthenosphere

• convection

• mesosphere

The sub-layer is a hot, dense, asphalt-like layer or rock that flows causing the plates of the Earth to move.

• lithosphere

• asthenosphere

• outer core

• inner core

Heat from the core causes these currents which slowly move the asthenosphere

• conduction

• convection

• radiation

• oceanic

The movement of liquid iron in the outer core is responsible for what?

• Continental crust

• ozone layer

• gravity

• magnetic field

What state of matter is the inner core?

• solid

• liquid

• gas

• plasma

Tags

NGSS.HS-ESS2-3

This layer of Earth's functions as our nuclear engine which heats everything else providing for the magnetic field, convection currents, and plate movement.

• crust

• mantle (asthenosphere)

• outer core

• inner core

What happens to the density from the crust to the core?

• The density increases (gets bigger)

• The density decreases (gets smaller)

• The density stays the same

• The density goes up and down depending on the layer

Why is the inner core solid even though it is very, very hot?

• It is under high pressure

• Iron and nickle can't become liquid

• The inner core is actually gas

• the inner core is frozen
