Be prepared to label a diagram

ik *=*

Earth's _ is solid and metallic.

inner core

Earth's core is composed mostly of

iron

Explain the DIFFERENCES between continental crust and oceanic crust

The continental crust is less dense and the oceanic crust is the most dense. Continental crust is under mountains and oceanic crust is under the ocean.

What is the plastic layer within the mantle called?

asthenosphere

flows like a soft plastic

asthenosphere

What his Earth's thinnest layer?

crust

What layer of the Earth is the least dense?

crust

includes soil, sentiments, and rocks

crust

List Earth's layers from least dense to most dense?

crust, mantle. core

Earth's is almost 13,000 km

diameter

What did scientists use to discover that Earth's core has two parts?

earthquake waves

made of iron crystals

inner core

List the Earth's layers from the center to the surface.

inner core, outer core, mantle, crust

How does pressure and temperature change as you move from Earth's crust to its core?

it increases

Is the outer core solid, liquid, or a plastic like substance?

liquid

Scientists group Earth's top two layers, which consist of rigid rock, into a layer they call the____________________________.

lithosphere

What is the crust and uppermost mantle called together?

lithosphere

includes the crust and rigid upper mantle

lithosphere

What is Earth's thickest layer?

mantle

the thickest layer of the Earth

mantle

What direction does a compass needlepoint in because of Earth's magnetosphere?

north

What two types of crust does Earth have?

oceanic crust and continental crust

What covers more than 70% of Earth's surface?

oceans

made of liquid metal

outer core

Name and describe the two parts of the core

outer core; made of liquid inner core; a dense ball of solid iron crystals

the least dense LAYER of the geosphere

outer layer

s the asthenosphere a solid, liquid, or a plastic like substance?

plastic like

What factor is greater at Earth's core than on its surface?

pressure

Think about Earth's layers and how they are structured. Explain whether an apple or peach would make a better model of Earth.

I think an apple would be the best because it has a core that represents the core, the actual apple part that represents the mantle, and the skin which represents the crust better than the peach.

Describe the magnetosphere, and evaluate it's importance for Earth.

The magnetosphere is a barrier type thing around Earth and protects us from Earth's cosmic rays.

Explain how the parts of a hard boiled egg, including the shell, correspond roughly to the Earth's layers

The shell represents the crust, the egg white represents the mantle, the yolk represents the core

Describe how temperature and pressure change within Earth's layers

The temperature and pressure increases the closer you get to the core.

How did the deep mines and wells give clues to the nature of Earth's interior

The temperature of the mines and wells and pressure will increase when it gets deeper

Name the four part of the mantle from top to bottom.

Uppermost mantle asthenosphere upper mantle lower mantle

Items that helped scientists learn about the inside of Earth

samples from deep wells, temperatures in deep mines, waves made by earthquakes
