The hottest major layer of the Earth.
What is the core?
The average thickness of the crust.
.The only physical layer of the Earth scientists have ever visited.
What is the lithosphere?
Pieces of the lithosphere that move around on top of the asthenosphere.
What is a tectonic plate?
It is the only fully liquid part of the Earth's interior.
The softer physical layer of the mantle.
What is asthenosphere?
The asthenosphere can be found between these two layers of the earth.
What is the crust and the mantle?
The waves produced by earthquakes which scientists study to determine the density and thickness of each physical layer of the Earth.
What are seismic waves?
It is the most dense part of the Earth.
What is the inner core?
Crustal plate movements are believed to be caused by these in the Earth’s mantle.
What are convection currents?
Granite is what these are mostly made of.
What are continental crusts made of?
The process in which hot material rises while cool material sinks.
Movement of Earth’s crust along plate boundaries produces these.
This is what causes the Earth to have a magnetic field.
What is convection of liquid metals in the outer core?
What physical layer of the earth is made of solid rock but flows very slowly?
These are made of mostly of basalt.
All layers of the Earth contain this substance or element.
The physical layer of the Earth that scientists believe is spinning on its own at a much faster rate than the rest of the Earth.
What is the inner core?
Solid part of the mantle under the lithosphere and the asthenosphere, but above the outer core.
These are two of the geologic features or events that may result from the movement of crustal plates.
What are earthquakes, volcanoes, rising magma, faulting, mountains, folding, trenches, plates move apart, new landforms, mid-ocean ridge, tsunami, and island?
