Feedback

• A process where information is used to adjust actions or signals.

• A loop in which a signal or action triggers another signal or action.

• A method of providing information to improve performance.

• A technique for gathering data from users.

Atmosphere

• The relatively thin layer of gases that forms Earth’s outermost layer.

• A thick layer of liquid that covers the Earth's surface.

• The solid outer layer of the Earth that includes the crust.

• A layer of ice that surrounds the Earth.

Cryosphere

• The portion of the hydrosphere that is frozen, including all the ice and snow on land, plus sea and lake ice.

• The area of the Earth where water is in liquid form, including oceans and rivers.

• The part of the atmosphere that contains water vapor and clouds.

• The region of the Earth that is covered by vegetation and forests.

Hydrosphere

• The layer of Earth that contains all living organisms.

• The portion of Earth that consists of water in any of its forms, including oceans, glaciers, rivers, lakes, groundwater and water vapor.

• The region of the Earth where the atmosphere meets the surface.

• The solid outer part of the Earth, including the crust and upper mantle.

Geosphere

• The outer layer of the Earth where life exists.

• The densest parts of Earth, including the crust, mantle, and core.

• The gaseous envelope surrounding the Earth.

• The liquid layer of the Earth beneath the crust.

Biosphere

• The parts of Earth that contain living organisms.

• The regions of Earth that are devoid of life.

• The areas of Earth that are only underwater.

• The parts of Earth that are exclusively inhabited by humans.

System

• A group of parts that work together as a whole.

• A single component that functions independently.

• An unrelated collection of items.

• A temporary arrangement of elements.

Energy

• The ability to do work or cause change.

• A measure of the amount of matter in an object.

• The force that opposes motion between two surfaces.

• A type of potential energy stored in an object.
