100

This seismic wave moves the fastest and go travel through solids liquids and gases.

What is a Primary Wave or P wave?

100

The crustal plates move on top of this part of the Earth.

What is mantle?

100

This is evidence of a weak spot in Earth's crust where magma an reach the surface.

What is a volcano?

100
Earthquakes and Volcanoes are usually located in relation to these
What is a plate boundary
100
The Himalayan mountains are the result of a ___________________________ boundary.
What is convergent boundary
200
A number of rigid, but moving, pieces of Earth's surface
What is tectonic plates.
200
The thickest layer of the Earth
What is the mantle.
200

This is how crustal plates move when forming folded mountains.

What is they move toward each other-convergent boundary?

200

The material circulation beneath the crust that moves the crustal plates.

What is molten rock?

200

Hot air or liquid is less ________________ than cool air or liquid.

What is dense?

300

The type of matter S or Secondary Waves travel through.

What is solids?

300
Plates float on top of the _______________________.
What is the asthenosphere
300

Compare transform boundaries and divergent boundaries.

What is transform boundaries slide past each other while divergent boundaries move away from each other?

300

These are formed at subduction zones.

What earthquakes and volcanoes?

300
_________________ are a result from the build up of stress at a plate boundary.
What is earthquakes
400

The way a seismic wave  moves during an earthquake

What is changes speed and direction as it moves through different material?

400
The rigid part of the Earth including the crust and the upper mantle (makes up the plates of the Earth)
What is the lithosphere
400

This boundary causes seafloor spreading.

What is convergent boundary?

400
This is the mechanism (what causes) the plates to move
What is convection cycles in the mantle
400

The San Andreas Fault in California is an example of a ____________________ boundary.

What is a transform boundary

500

This occurs when continental crust collides with another continental crust.

What is a mountain?

What is thinnest under the ocean and thickest under the continents.
500

DOUBLE JEOPARDY

The mid-ocean ridge is an example of a ____________________ boundary and ___________________ occurs here where new ocean floor is formed.

What is divergent boundary; sea-floor spreading?

500
The two types of convergent boundaries
What is subduction (where volcanoes often occur) and collision (where mountains are usually formed)
500

DOUBLE JEOPARDY

This is the reason Iceland has so many active volcanoes.

What is it lies over 2 colliding tectonic plates?
