100
Continual process by which new rock forms from old rock material..
What is the rock cycle?
100
Three layers of the Earth.
What are crust, mantle and core?
100
A break in the Earth's crust along which blocks of the crust slide releative to one another.
What is a fault?
100
Instrument located at or near surface of Earth that record seismic waves.
What is a seismograph?
100
Magma that flows onto the surface of the Earth.
What is lava?
200
Movement within the earth that causes rocks inside the Earth to be moved to the Earth's surface.
What is uplift?
200
Pieces of the lithosphere that move around on top of the asthenosphere.
What are tectonic plates?
200
Plastic or elastic deformation causes earthquakes.
What is elastic?
200
The point on the Earth's surface directly above an earthquake's starting point.
What is the epicenter?
200
True or False All volcanic eruptions are explosive.
What is False? The most common type of eruption is non-explosive.
300
Intense heat and pressure squeeze sedimentary rock and change it.
What is metamorphic rock?
300
A supercontinent from 245 million years ago.
What is Pangea?
300
Three kinds of tectonic plate boundaries.
What are convergent, divergent and transform?
300
Point inside the Earth's surface where earthquake begins.
What is focus?
300
Besides magma, this is the other ingredient that causes an eruption.
What is water?
400
Grains of sediment are compacted and cemented together.
What is sedimentary rock?
400
Hypothesis of continental drift creator?
Who is Alfred Wegener?
400
Waves of energy that travel through the Earth.
What are seismic waves?
400
Richter magnitude scale measures?
What is strength of earthquakes?
400
When magma builds up beneath a volcano, a large amount of pressure is created. Is this pressure potential or kinetic energy at this point?
What is potential? Magma is only exerting pressure on surrounding rock but not moving, therefore not kinetic.
500
Magma cools and solidifies to form this rock type.
What is igneous rock?
500
The speed at which tectonic plates moves can be measured as...
What are cm per year? cm/yr
500
Seismic wave is traveling through Earth at average rate speet of 8 km/s. How long will it take wave to travel 480 km?
What is 1 minute? 480km -:- 8km/s = 60 s = 1 m
500
Scale used by seismologists to measure intensity of earthquake damage.
What is Modified Mercalli Intensity Scale?
500
What effect might volcanic eruption have on the climate of an area?
What is a decrease in global temperature? Because the ash can block out the sun for long periods of time, the temperature would be decreased.
