Vocabulary
movement and interaction of the Earth's plates.
Number of layers of the Earth.
What is 4?
Most earthquakes and volcanic eruptions occur along _____ _______.
What are Faults/Plate Boundaries?
Giant waves caused by earthquakes or volcanic eruptions under the sea.
What are Tsunamis?
Number of continents on Earth?
What is Seven?
A person who studies the physical formations of the Earth.
What is a geologist?
Although the hottest layer of the Earth, this layer is solid metal.
What is the Inner Core
This type of plate boundary involves two plates moving toward each other.
What is a convergent boundary?
The result from the build up of stress at a plate boundary - causes a sudden shaking of Earth's crust.
Earthquake
This is the average distance the earth's plates move per year.
What is 1 inch per year?
Rigid, but moving, pieces of Earth's crust.
What are tectonic plates?
Outer-most layer of the Earth. Also, the thinnest layer.
What is the Crust?
This type of plate boundary involves two plates moving apart from one another.
What is a divergent boundary?
These are formed by subduction interactions.
What are trenches?
These are the two types of evidence that were initially used to support the Theory of Continental Drift.
What are similar shapes of coastlines and fossil evidence?
A supercontinent - when all the contents were originally one large land mass.
What is Pangea?
These are the two types of crust.
What is the Continental Crust and Oceanic Crust?
This type of plate boundary involves one plate sliding past another plate.
What is a transform boundary?
an opening in the Earth's crust, through which lava, ash, and gases erupt, and also the cone built by eruptions.
What is a volcano?
Deepest part of Earth's crust.
What is the Challenger Deep (in the Mariana Trench)?
The movement of continents resulting from the motion of tectonic plates.
What is continental drift?
Tectonic plates float on top of this layer. It is also the thickest layer.
What is the Mantle?
This interaction happens when a plate with thinner crust descends beneath a plate with thicker crust.
What is subduction?
These form where two continental plates collide. Since both plates have a similar thickness and weight, neither one will sink under the other.
What are mountains?
massive slab of solid rock made up of Earth's crust.
What is a continent?
