Parts of the Earth
The rigid outer part of the Earth that is made up of the upper crust and the mantle.
What is the Lithosphere?
A rock formed by crystallization of molten Magma.
What is an Igneous Rock?
The point beneath the Earth's surface where rock breaks under stress.
What is the focus?
The process where plate tectonics produce new oceanic crust at ocean ridges.
What is Seafloor spreading?
The resistance of flowing or the thickness of/in a liquid.
What is viscosity?
The soft layer of the mantle below the Lithosphere.
What is the asthenosphere?
A rock formed by weathered products of rocks before it was made and compacted into a new rock.
What is a Sedimentary Rock?
The point directly above the focus of an earthquake.
What is the Epicenter?
A plate boundary where the 2 plates move away from each other.
What is a divergent boundary?
The transportation of a material usually by ice, water or ice.
What is erosion?
A natural Inorganic solid, that has a crystal structure.
What is a mineral?
A rock that has been altered by heat, pressure and/or chemicals.
What is a Metamorphic rock?
A fracture in the Earth which movement of the plates has occurred.
What is a Fault?
A plate boundary where 2 plates move into each other.
What is a transform boundary?
A natural resource that can be replaced faster than we can use it.
What is a renewable resource?
A body of molten rock found at depth, which includes gases and crystals.
What is Magma?
Loose Particle by weathering and erosion of rock.
What are sediments?
Vibrations that travel through the Earth during an earthquake.
What are seismic waves?
A concentration of heat in the mantle that produces Magma and causes the surface to rise.
What is a hot spot?
A natural resource that cannot be replenished quickly.
What is a nonrenewable resource?
Magma that is on the Earth's surface.
What is Lava?
The process that makes rocks break down by chemical reactions.
What is Chemical weathering?
A device that records seismic wave activity.
What is a Seismograph?
A plate boundary where 2 plates slide past each other.
What is a transform boundary?
The process in where rock is physically broken down into smaller pieces without changing the composition.
What is mechanical weathering?
