Earth's Structure
What are the three layers of the Earth?
What are the core, the mantle, and the crust?
These pieces of the crust fit together like a jigsaw puzzle.
What are tectonic plates?
This happens when an earthquake occurs.
What is the ground shakes?
Volcanoes are formed when this happens.
What is magma pushed out a crack between two tectonic plates.
This is the name for molten rock that has reached the surface.
What is lava?
This layer is at the center of the earth and is VERY hot and has SO MUCH pressure.
What is the core?
Tectonic plates float on top of this layer of the Earth.
What is the mantle?
These ripples in the land occur when an earthquake happens.
What are waves?
This is the largest volcano, and it is located in Hawaii.
What is Mauna Loa?
This is the name for molten rock below the earth's surface.
What is magma?
This layer is made of hot melted rock.
What is the mantle?
This is the reason you cannot feel the land under your feet moving.
What is the plates move VERY slowly?
These two words are the names for where an earthquake starts below and above the surface of the earth.
What are epicenter and focus?
There are many volcanoes that show scientists where plate boundaries are in the Pacific Ocean, and these volcanoes are called this.
What is the Ring of Fire?
This is the name for something that is hot and melted.
What is molten?
This layer is an average of 24 miles thick and sits on top of liquid rock.
What is the crust?
This is how slow the tectonic plates move.
What is the speed of your fingernails growing?
When an earthquake occurs in the ocean, one of these can form, causing a tremendous amount of damage when it reaches land.
What is a tsunami?
Underwater volcanoes have created this state in our United States.
What is Hawaii?
This is the name for when two tectonic plates move away from each other.
What is divergent?
The L_______________ is between the crust and the mantle.
What is the lithosphere?
Alfred Wegener was famous for this theory, but no one believed him.
What is the idea that crust is made up of moving plates, or plate tectonic?
This is the name of the scale used to measure the intensity of an earthquake.
What is the Richter Scale?
This type of rock is formed by cooled lava from a volcanic eruption.
What are igneous rocks?
This is the name for two tectonic plates moving into each other.
What is convergent?
