Earth: Our Home
This is the science of Earth's structure.
Geology
This the outermost layer of the Earth, which is solid and made of rock.
The Crust
These are the large plates the Earth’s surface is divided into.
Tectonic Plates
This is the sudden movement of a fault, usually caused by the motion of tectonic plates colliding, separating, or sliding.
This is a mountain that forms when molten rock, or magma, reaches the Earth’s surface.
Volcano
This is a scientist who studies the Earth's structure.
Geologist
This is the thickest layer of the Earth, made of magma.
Mantle
This is when one tectonic plate pushes under the other.
Collide
This is a large crack within Earth along which sections of rock move past one another.
Fault
This is magma that reaches Earth’s surface.
Lava
Name all five oceans.
Atlantic Ocean, Pacific Ocean, Indian Ocean, Arctic Ocean, and Southern
This is thick liquid with a consistency similar to oatmeal.
Magma
This means to move apart.
Separate
This is the location within Earth where an earthquake occurs.
Focus
When do most volcanoes form?
Where plates collide or separate.
Name all seven continents.
North America, South America, Europe, Asia, Africa, Australia/Oceania, and Antarctica.
This is the area below the mantle, made up of liquid iron and nickel.
Outer core.
This is when plates rub against each other and cause earthquakes.
Slide
This is the location on the Earth’s surface directly above the focus.
Epicenter
Name an Island formed by volcanoes.
Hawaii or Iceland
Millions of years ago, all of the continents were together as one supercontinent. What was it called?
Pangaea
This is the innermost layer of the Earth, made of solid nickel and iron.
Inner core.
What happens when plates collide?
Once plate pushes under the other, causing mountains, earthquakes, and volcanoes.
This a large mass of moving water caused by a strong earthquake under the ocean.
What is the difference between magma and lava?
Magma is melted rock before leaving a volcano, and lava is melted rock after leaving a volcano.
