What is the solid dense center of our planet called?
Inner core
100
What is the uppermost part of the mantle plus the crust, which is divided into tectonic plates?
Lithosphere
100
What is the boundary called when two tectonic plates slide past each other horizontally?
Transform Boundary
100
What type of mountain is the only one that is formed by adding new material to Earth's surface?
Volcanic
100
What type of stress is being put on a rock when it is stretched?
Tension
200
Which layer makes up most of Earth's mass?
The Mantle
200
What is the soft layer of the mantle on which pieces of the lithosphere move?
Asthenosphere
200
What land form is associated with divergent boundaries on oceanic crust.
Mid-ocean ridges
200
What happens when rock layers bend due to stress?
Folding
200
How do temperature and pressure change as you go deeper into the Earth?
They increase
300
Is Earth's oceanic crust thinner or thicker than continental crust?
It is thinner.
300
Where do most Earthquakes occur?
Along or near the edges of tectonic plates.
300
What boundary is formed when two tectonic plates move away from one another?
Divergent
300
How does stress in the crust change Earth's Surface?
It pushes rock masses together, it pulls rock masses apart, and it causes rock masses to slide passed one another.
300
What kinds of indirect evidence do geologists use to study Earth's interior?
Volcanic rocks and seismic waves
400
Which layer of Earth's interior is responsible for Earth's magnetic field?
Outer Core
400
What appears to cause the movement of Earth's Tectonic Plates?
Convection currents below the lithosphere.
400
What type of tectonic plate boundary involves collision between two plates?
Convergent
400
Where are volcanic mountains most likely to form?
Along plate boundaries
400
Place these terms in correct order so they begin at Earth's surface and move toward the center: inner core, asthenosphere, lower mantle, lithosphere, outer core.
