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 a naturally occurring solid composed of minerals, rock fragments, and sometimes other material such as organic matter
The study of earth's history as revealed in the rocks that make up the earth Geology, of that studying rocks onearthscrust.Geologist know that earth's landforms work of natural forces that build up and and wear down on 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 land masses through a process like erosion and weathering Destructive forces are those that slowly wear away mountains.
one of Earth's seven large land areas There are seven great land masses called continents,surrounded by oceans.
a ground vibration produced by an earthquake. The closer to the epicenter, the stronger these waves are felt. When there are earthquakes they produce seismic wave.Geologist 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. 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 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 oceanic crust made mostly of basalt.
