This theory was proposed by Alfred Wegener who claimed that all of the continents were once joined together like a jigsaw puzzle then slowly moved apart.
What is CONTINENTAL DRIFT?
100
This force is caused by plates pushing together to form folded mountains.
What is COMPRESSION?
100
This is an opening in Earth's crust through which melted rock flows.
What is A VOLCANO?
100
This is a sudden shaking of Earth's crust caused by the slipping of stuck plates at a fault.
What is an EARTHQUAKE?
200
This very low area is between hills or mountains.
What is a VALLEY?
200
These make up the Earth's crust and fit together like a puzzle. They move on the melted rock in the mantle.
What are TECTONIC PLATES?
200
This force is caused by two plates rubbing past each other. This twisting pushes one part of the crust past another forming fault-block mountains.
What is SHEAR?
200
This happens when pressure causes magma to rush up through the vent of a volcano.
What is a VOLCANIC ERUPTION?
200
Waves of energy are made here where the slipping of plates begins.
What is THE FOCUS?
300
This is a very shallow part of the ocean along the coast of a continent.
What is the CONTINENTAL SHELF?
300
These were found in South America and Africa, and being from the same reptile, confirmed the idea that the continents have moved apart.
What are FOSSILS?
300
The Himalayas are these kind of mountains.
What are FOLDED MOUNTAINS?
300
This is a volcano that stops erupting or is "dead".
What is EXTINCT?
300
This is the point on Earth's surface where waves of energy spread out causing an earthquake.
What is an EPICENTER?
400
This is the layer of gases that surround the Earth.
What is the ATMOSPHERE?
400
This melted rock moves up to the surface and cools to form the mid-ocean ridge and the rift valley.
What is MAGMA?
400
These are deep cracks in the Earth's crust.
What are FAULTS?
400
This is a fixed pool of magma that causes the formation of a chain of volcanic islands, such as the Hawaiian Islands, as a plate moves above it.
What is a HOT SPOT?
400
This is a measure of how much energy an earthquake releases.
What is MAGNITUDE?
500
This is the rocky layer of Earth's surface which sits above the mantle.
What is the CRUST?
500
This theory states that the Earth's crust is made of moving plates.
What is PLATE TECTONICS?
500
When this happens mountains are formed?
What is PLATES PUSHING TOGETHER?
500
Where this happens, volcanoes tend to erupt as rock fall down into the mantle and melt.
What is ONE PLATE BEING PUSHED UNDER ANOTHER?
500
This can happen when an earthquake happens under the ocean with a magnitude of at least 6.5 on the Richter scale.
