QuestionAnswer
A scientist who studies the forces that make and shape planet Earth an expert in geology, the study of what the Earth is made of and how it was formed
a naturally occurring solid composed of minerals, rock fragments, and sometimes other material such as organic matter Geologists study the forces of earth. Geologists study a chemical and physical features of rocks.
The study of earth's history as revealed in the rocks that make up the earth Geology, of that studying rocks on earth's crust. Geologists know that earth's landforms work of natural forces that build up and wear down the land.
shape Earth's surface by building up mountains and land masses Constructive forces shape the surface by building up landmasses.
Destroys and wears away landmasses through a process like erosion and weathering Destructive forces are those that slow wear away mountains.
one of Earth's seven large land areas There are seven great landmasses called continents, surrounded by oceans.
a ground vibration produced by an earthquake. The closer to the epicenter, the stronger these waves are felt. When earthquakes come they generate seismic waves. Geologists record the seismic waves and study how they travel through the earth.
the force being exerted on some part of Earth's structure due to gravity or the movement of its layers. Pressure is the force pushing on a surface. Because of the weight above.
The outermost layer of solid rock that includes both dry land and the ocean floor. The thinnest layer of the Earth. The crust beneath the ocean is called oceanic crust. Oceanic crust is a dense rock such as basalt. Basalt is a dark, dense rock with a unique texture.
A dark, dense, igneous rock with a fine texture, found in oceanic crust. Basalt is a dark dense rock with a fine texture. Continental crust is the crust that forms a fine texture.
the most abundant rock in the continental crust. Continental crust, the crust that forms the continents, consists mainly of less dense rocks such as granite.
The thick layer of hot, solid material between Earth's crust and core that has convection currents A trip through earth's mantle goes almost halfway to the center of the earth.
The crust and upper mantle of the Earth that is solid and rigid. The rigid crust and lithosphere float on the hot plastic material of the asthenosphere.
The soft layer of the mantle on which the lithosphere floats. lithosphere floats on the hot, plastic material of the asthenosphere. Notice that continental crust, made mostly of granite, is several times thicker than the oceanic crust, made mostly from basalt.
a layer of molten metal, mainly nickel and iron, that surrounds Earth’s inner core. Scientists estimate that temperatures within earth's outer core and inner core, both made of iron and nickel, range about 2,000 degrees celsius to 5,000 degrees celsius.
A solid sphere of iron and nickel at the center of the earth. Inner core, both made of iron and nickel go to about 2,000 degrees celsius.
the movement of energy from a warmer object to a cooler object. The movement of energy from a warmer object to a cooler object to a cooler object is called heat transfer.
Heat transport through empty space Heat transfer by radiation takes place with no direct contact between a heat source and an object.
Heat transport by direct contact of energy from one particle to another, without moving the particle to a new location. When your hand touches a hot spoon, conduction transfers heat from the spoon directly to your skin.
Heat transport by a heated fluid caused by a difference in temperature and density. Convection is heat transfer by the movement of heated fluid.
in a fluid material. Responsible for the movement of the Earth's Plates. flow that transfers heat within fluid.
