Earth
Which layer of the earth is the thin, solid outer layer that we live on?
Crust
What is the main difference between the outer core and inner core?
Outer Core is liquid and inner core is solid
Why is the movement of tectonic plates important?
It causes earthquakes, volcanoes, mountains, and other changes to earths surface.
What is an earthquake?
A sudden shaking of Earth's surface
What is magma?
Melted rock beneath Earth's surface
Which layer of Earth is the thickest?
Mantle
What is the lithosphere?
The outer layer and part of the mantle
What can happen when two tectonic plates move toward each other?
They collide and cause mountains, earthquakes or volcanoes.
Most earthquakes are caused by—
Tectonic plates suddenly moving along faults
What is Lava?
Melted rock that reaches Earth's surface
Which layer is made mostly of solid iron and nickel?
Inner Core
What are tectonic plates?
Large Pieces of the Earth's Lithosphere
What can happen when two tectonic plates move away from each other?
New crust can form.
Where do earthquakes commonly occur?
Along or near tectonic plate boundaries
How can tectonic plate movement cause a volcanic eruption?
Plate movement causes magma to rise towards the surface
Which layer of Earth is liquid?
Outer core
What causes tectonic plates to move?
Movement and heat from the mantle
What can happen when two tectonic plates slide past each other?
Earthquakes!!!!!
Explain how tectonic plate movement can cause an earthquake.
When plates move at transform boundries they slip past each other cause an earthquake.
A student says, “Earth's surface never changes because the crust is solid.” Is the student correct? Explain why or why not.
FALSE. IT IS ALWAYS MOVING
Put the layers of Earth in order from the outside to the inside.
1. Crust
2. Mantle
3. Outer Core
4. Inner Core
The lithosphere is broken into large pieces called __________________________.
Techtonic Plates
Explain how the movement of tectonic plates can change Earth's surface.
They create new things.
What is a volcano?
An opening in Earth's crust where magma can reach the surface
Imagine two tectonic plates suddenly push against each other. Name TWO events or landforms that could result from this movement.
Earthquakes, trenches, Volcanoes, Mountains
