The deepest layer inside the Earth is the:

Inner core

100
A sudden shaking or vibrations on Earth’s surface caused by sudden movement on Earth, often along a fault, a break in the Earth’s surface
What is an earthquake?
100
Substance that flows out of volcanoes
What is lava?
100
Theory that earth's lithosphere (crust) is divided into plates that move is known as...
What is plate tectonics?
100

What is pyroclastic material?

What is high-density mix of hot lava blocks, pumice, ash and volcanic gas. They move at very high speed down volcanic slopes, typically following valleys.

200

Pieces of the lithosphere (crust) that move around on top of the earth:

What are Tectonic plates?

200
Deep cracks in the Earth's crust, where blocks slide against one another causing an earthquake
What are faults?
200
Hot soft liquid rock that is within the mantle.
What is magma?

Plates that move away from each other are called?

What is divergent boundary?

200
the process of moving sediment from one place to the next.
What is erosion?
300
The theory that continents can drift apart from one another and have done so in the past.
What is Continental Drift?
300
A scientist who studies rocks and learns about how the Earth is made up
What is a geologist?
300
A mountain formed by lava and ash.
What is a volcano?
300

What is a fissure?

Is a long, narrow crack or linear opening in the Earth's crust

Why are there so many volcanoes at the Ring of Fire

Caused by the amount of movement of tectonic plates in the area.

400

The downhill movement of soil due to water.

What is erosion?

400

The place where an earthquake begins.

What is the focus?

400

Three types of volcanoes.

What are Shield, Cinder Cone and Composite volcanoes?

400

The heaviest tectonic plates...

What are oceanic?

400
The dropping or depositing of sediment by water, wind, or ice which can build "up" new land like a sand dune or a delta or sea shells on a beach
What is Deposition?
500

The process of breaking rock into soil.

What is weathering?

500

Plates can interact in three ways.

What is they push together, pull apart and slide past each other?

500
Numerous volcanoes lying directly on tectonic plate boundaries in the Pacific Ocean form this
What is the Ring of Fire

What happens at a convergent plate boundary?

When two plates come together,

How do fossils support the theory of continental drift? Think of our Pangaea paper.

Fossils of similar plants and animals have been found in different places that were once connected.
