Inside Earth Test 1

Inside Earth Vocabulary Test

Continental Drift Theory by Alfred Wegener
Pangaea Means "all lands"
Glossopteris Fern like fossil
Lithosphere Layer of rigid or hard rock
Asthenosphere Layer of soft rock
Plate Tectonics Theory by J Tuzo Wilson
Subduction When one plate dives under another
Rift Valley Deep valley that forms when two plates move apart on land
Deep Sea Trench Deep valley in the ocean where the crust sinks towards the mantle
Mid-Ocean Ridge Undersea mountain made by a divergent boundary
Transform Plate Boundary When two plates are sliding past each other, opposite directions.
Convergent Plate Boundary When two plates go closer to each other.
Divergent Plate Boundary When two plates go far away from each other.
Seafloor Spreading When new crust is made on the ocean floor due to a divergent boundary.
Constructive Force Shapes the surface by building mountains and landmasses.
Destructive Force Those that slowly wear away mountains and, eventually, every other feature on the surface.
Continents Are seven landmasses.
Seismic Wave A vibration that travels through Earth carrying the energy released during an earthquake.
S wave A type of seismic wave that moves the ground up and down or side to side.
Temperature As you travel down deep into the earth, this starts to increase.
Pressure As you travel deep into the earth, this also starts to increase.
Magma The molten mixture of rock-forming substances, gases, and water from the mantle.
Granite A usually light-colored rock that is found in continental crust.
Basalt A dark, dense, igneous rock with a fine texture, found in oceanic crust.
Crust The layer of rock that forms Earth's outer surface.
Earthquake The shaking that results from the movement of rock beneath Earth's surface.
Geology The study of planet Earth.
Hot Spot An area where magma from deep within the mantle melts through the crust above it.
Igneous Rock A type of rock that forms from the cooling of molten rock at or below the surface.
Lava Liquid magma that reaches the surface; also the rock formed when liquid lava hardens.
Mantle The layer of hot, solid material between Earth's crust and core.
Inner Core A dense sphere of solid iron and nickel in the center of Earth.
Outer Core A layer of molten iron and nickel that surrounds the inner core of Earth.
P wave A type of seismic wave that compresses and expands the ground.
Plate A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust.
Rock The materials that forms Earth's hard surface.
Sedimentary Rock A type of rock that forms when particles from other rocks of the remains of plants and animals are pressed and cemented together.
Density A me sure of how much mass there is in a volume of a substance.
Conduction Heat transfer by direct contact of particles of matter.
Convection Heat transfer by the movement of a heated fluid.
Convection Current The flow that transfers heat within a fluid.
