What are the layers of the earth?
Crust:
Mantle:
Outer Core:
Inner Core:
Constructive Force -Natural forces that build or construct landforms
Destructive force- Natural forces of earth that destroy landforms and cause damaging
changes in the Earth’s surface
Geologist -A scientist who studies Earth.
Seismologist -A scientist who studies earthquakes
Seismograph -A device that records the motion of Earth’s crust.
Fault -A crack, break, or a defect in the earth’s crust
Weathering -A slow process that uses temperature, gases, and water to break down rocks
and other substances into smaller pieces.
Physical Weathering -Process by which rock is physically broken into smaller pieces, but
maintains its original material.
Chemical Weathering -Due to this process, rock is broken down through chemical
changes and the chemical properties are altered within a rock.
Landforms -Mountains, volcanoes, plains, plateaus, and other solid features of the earth’s
surface.
Volcano -A mountain that forms when hot melted rock flows through a crack onto the
surface of the earth. It is sometimes thought of as both a constructive and destructive
force.
Earthquakes -The process of shifting the plates under the earth’s surface. Occurs when
the crust on either side or on both sides are in motion.
Erosion-The process by which natural forces pick up and carry away pieces of rock and soil
from one place to another.
Deposition -The process that is driven by gravity and drops off of bits of eroded rock in a
new place.
Transport of Sediment -A means of changing the Earth's surface by the movement of dirt
and rocks in flowing water.
Weathered rock -Rock that has been broken down by chemical or physical changes
Levee -man made structure that helps keep the flow of water inside a river
