Earth Composition
This is the thin outer skin of the earth.
What is the crust?
This material is underneath the earth's surface and is hot.
What is magma?
These large bodies of ice stay frozen all year and can change the surface of the earth.
What are glaciers?
This is a deep valley in the ocean where two plates move apart.
What is a rift?
This layer of earth is the deepest, be specific.
This material is above the earth's surface and is hot.
What is lava?
These shaking events are caused by tectonic plates and can cause damage on a massive scale or barely be felt.
What are earthquakes?
This the surface location that is above an earthquake.
What is the epicenter?
This layer is directly under the crust.
What is the mantle?
These things can form when magma is released as lava on the surface.
What are volcanoes?
This instrument is used to detect earthquakes.
What are seismographs?
This type of volcano is formed by violent eruptions.
What are cinder cone volcanoes?
This layer of earth consists of the crust and the uppermost part of the mantle.
What is the lithosphere?
Give the layers of the earth in the correct order, from the deepest to the surface.
What is the inner core, the outer core, the mantle, and the crust?
This is the boundary of two tectonic plates.
What is a fault?
This is where seafloor spreading occurs.
What is along a mid-ocean ridge?
This layer of earth produces earth's magnetic field.
What is the outer core?
This allows the lithosphere to move.
What is the asthenosphere's ability to flow?
This is the point inside the earth where an earthquake occurs.
What is the focus?
This is the removal and transportation of weathered material.
What is erosion?
