Don't "Stress" Out!
Tension, compression, and shearing.
What are the types of stress?
Wegener idea that landmasses had once been fused together is called this.
What is Continental Drift?
This is molten mixture of rock from the mantle.
What is magma?
A large wave caused by an earthquake or landslide.
What is a tsunami?
The fastest kind of wave.
What is a "P" wave?
The force that acts on rocks to change its shape or volume.
What is stress?
Evidence to support Wegener included fossils, land features and this.
What is climate data?
This type of volcano has layers of lava and ash.
What is a composite volcano?
Movement of rock down a slope.
What is a landslide?
A break in the rock of the Earth's crust or mantle.
What is a fault?
This is when rocks get pushed into two different directions.
What is shearing?
This was a super continent that existed during the late Paleozoic and early Mesozoic eras.
What is Pangea?
A volcano that still has lava that flows out of it from time to time is considered this.
What is active?
The shaking and trembling that results from the movement of two plates.
What is an earthquake?
The most destructive wave.
What is a surface wave?
When the earth is pulled and stretches the earth to make it thinner.
What is tension?
Plates slip past each other. (ex: San Andreas Fault)
What is transform boundary?
An instrument that can be used to detect rumblings deep inside a volcano.
What is a seismograph?
This is the energy released by an earthquake.
What is the magnitude of an earthquake?
Most are found at convergent plate boundaries.
What is a volcano?
This stress can squeeze rock together until it bends or breaks.
What is compression?
This happens when plates come together or collide.
What are convergent boundaries?
A slow and steady flow of magma can form this type of volcano.
What is a shield volcano?
Waves strike the quickest & with the most energy here.
What is the epicenter?
This is where molten rock is held.
What is the magma chamber?
