Topic 3
This type of rock forms from the cooling of molten rock at or below the surface.
What is igneous rock?
This theory states that the continents had once been fused together and that over time they had drifted apart.
What is The Continental Drift Theory?
_________ is a molten mixture of rock-forming substances, gases, and water from the mantle while _________ is liquid magma that reaches the surface.
What is magma and lava?
As you move deeper into Earth's layers, how does pressure change?
What is pressure increases?
This is a wave or series of waves produced by an earthquake or a landslide.
What is a tsunami?
These are long, zipper-like chains of undersea mountains.
What is a mid-ocean ridge?
This type of rock forms when particles from other rocks or the remains of plants and animals are pressed or cemented together.
What is sedimentary rock?
What is the difference between an active and a dormant volcano?
What is an active volcano can erupt at any time while a dormant volcano is not currently active but is able to become active in the future?
This is the sinking movement of ocean floor back into the mantle. It occurs when a dense plate of oceanic crust goes under an adjacent section of Earth's crust.
What is subduction?
This type of rock forms from an existing rock that is changed by heat, pressure, or chemical reactions.
What is metamorphic rock?
Name the three types of boundaries and describe each one.
What is a
Divergent boundary- plates move apart
Convergent boundary- plates come together
Transform boundary- plates slip past each other
These are undersea valleys that are the deepest parts of the ocean. It is where subduction occurs.
What are ocean trenches?
What is the difference between a streak test and a luster test?
What is during a streak test, you scratch the mineral on a streak plate. The streak is the color of its powder. For a luster test, you look closely to see how light reflects from the mineral's surface?
What evidence supports the Continental Drift Theory?
What is mountain ranges seem to line up near the continents' coasts, fossils of plants and animals were found on many continents, and climate has changed over time?
This occurs when rock is being pushed in two opposite directions to the point that it bends or breaks. This occurs when rock is squeezed until it bends or breaks.
What is shearing?
What is compression?
