A scientist who studies the forces that make and shape planet Earth | geoligists |
a naturally occurring solid composed of minerals, rock fragments, and sometimes other material such as organic matter | rock |
shape Earth's surface by building up mountains and land masses | constructive forces |
Destroys and wears away landmasses through a process like erosion and weathering | destructive forces |
one of Earth's seven large land areas | continent |
a ground vibration produced by an earthquake. The closer to the epicenter, the stronger these waves are felt. | seismic waves |
the force being exerted on some part of Earth's structure due to gravity or the movement of its layers. The outermost layer of solid rock that includes both dry land and the ocean floor. The thinnest layer of the Earth. | pressure |
A dark, dense, igneous rock with a fine texture, found in oceanic crust. | basalt |
the most abundant rock in the continental crust. | granite |
The thick layer of hot, solid material between Earth's crust and core that has convection currents | mantle |
The crust and upper mantle of the Earth that is solid and rigid. | lithoshere |
The soft layer of the mantle on which the lithosphere floats. | athenoshpere |
a layer of molten metal, mainly nickel and iron, that surrounds Earth’s inner core. | outer crust |
A solid sphere of iron and nickel at the center of the earth. | iner core |
the movement of energy from a warmer object to a cooler object. | heat transfer |
Heat transport through empty space | radiation |
Heat transport by direct contact of energy from one particle to another, without moving the particle to a new location. | conduction |
Heat transport by a heated fluid caused by a difference in temperature and density. | convectioin |
Heat movement in a fluid material. Responsible for the movement of the Earth's Plates. | convection current |
The amount of mass in a given space. | density |
