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
