Terms in this set (25)
The outermost solid compositional layer of Earth.
Compositional layer of hot, slow-flowing solid rock.
The densest compositional layer; made of metal.
Earth's crust located under the ocean.
The portion of the Earth's crust that makes up the continents and is less dense than oceanic crust.
The crust, mantle, and core are made up of a different mixture of chemicals.
A dense sphere of solid iron and nickel at the center of Earth.
The liquid metal layer of the Earth's core that lies beneath the mantle.
convection currents in the mantle
The movement of hot rock rising and cooler rock sinking.
The lithosphere, asthenosphere, mesosphere, outer core, and inner core are separated based on properties such as whether the layer is solid or liquid and how the layer moves or transmits waves.
The outermost, rigid physical layer of the Earth that consists of the crust and upper part of the mantle; divided into tectonic plates.
The soft physical layer of the mantle, made of rock that flows slowly; tectonic plates move on top of this layer.
The strong, lower part of the mantle; rock in this physical layer flows more slowly than rock in the asthenosphere does.
increases as you go deeper into the Earth.
The movement of energy from a warmer object to a cooler object.
The energy transferred between objects that are at different temperatures.
The direct transfer of heat from one substance to another substance that it is touching.
Process by which, in a fluid being heated, the warmer part of the fluid will rise and the cooler portions will sink.
Energy that is transmitted in the form of electromagnetic waves.
Consists of all life on Earth.
All the liquid waters on Earth, such as lakes, seas, and clouds.
Part of Earth's system that includes all water that is frozen in polar ice caps, snow, permafrost, and glaciers.
A thin layer of gases surrounding Earth.
The solid parts of the Earth consisting of rocks (inside and outside Earth), minerals, landforms, and the processes that shape Earth's surface.
All of the matter and energy within Earth's boundary; consists of 5 spheres.
