Our Globe
Is the International Date Line is this kind of line on the globe.
Longitudinal
The Pacific Plate and the North American Plate
This happens to the tension on rocks after an earthquake.
It is decreased
Magma when it reaches the surface of the earth.
Lava
Crystalline structures that are found in nature
Minerals
This part of the Earth does NOT have four seasons.
Near the Equator
This is happening in the Mid-Atlantic Ridge... (subduction or seafloor spreading)
Seafloor spreading
These play a big role in whether buildings stand in an earthquake.
engineering design and materials used to build
The measurement scale used to detect earth tremors.
The Richter Scale
These have flat faces and a definite shape that rocks do not.
Crystals
This is the layer of the Earth found directly beneath the crust.
Mantle
This happens often along the San Andreas Fault.
Earthquakes
This is where earthquakes are most prone to occur.
Along fault lines.
The year the Island of Surtsey first appeared.
1963
These are the minerals found in granite (defined as a rock)
Quartz, Mica, and Feldspar
The earth's crust is the thicker here than in the ocean.
Under Land
The Himalayan Mountains are thought to have formed when two crustal plates did what?
Collided into one another.
Along this famous connected line of faults there are many volcanoes and earthquakes.
Ring of Fire
Rocks that cool and harden from hot magma BELOW the surface of the earth.
Intrusive Rocks
The two conditions generally necessary in order to form metamorphic rocks.
Heat and Pressure
These may cause the earths' crust to slowly move and play a role in producing the earth's magnetic field.
Convection - type currents
This may have been the original land mass.
Pangaea
According to this, rocks break loose from a position of tension and surge forward.
The Elastic Rebound Theory
Dikes and sills are both examples of these kinds of rocks.
Intrusive Rocks
These are the three main groups of rocks - igneous, sedimentary, and _____
metamorphic
