The shape of the land determined by elevation, relief, and landforms

A feature on the surface of Earth, such as coastline, dune, or mountain

A landform with high elevation and high relief

A line that forms the boundary between land and the ocean or lake

A hill of sand piled up by the wind

A natural stream of water that flows into another body of water, such as an ocean, lake, or another river

A landform made of sediment that is deposited where a river flows into an ocean or lake

A process in which mapmakers determine the distance and elevation using instruments and the principles of geometry

The continual movement of water among Earth's atmosphere, oceans, and land surfaces through evaporation, condensation, and precipitation

The process by which molecules at the surface of a liquid absorb enough energy to change into a gas

The process by which water is lost through a plant's leaves

The change of state from a gas to a liquid

The process by which atoms are arranged to form a material with a crystal structure

A type of rock that forms from the cooling of molten rock at or below Earth's surface

A type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together

Small, solid pieces of material that come from rocks or the remains of organisms; Earth materials deposited by erosion

A type of rock that forms from an existing rock and is changed by heat, pressure, or chemical reaction

A series of processes on the surface of Earth that slowly changes rock from one kind to another
