Tema 8: La hidrosfera

Hydrosphere: all the water found on Earth, including oceans, rivers, glaciers, and water vapor in the air.

Water cycle: the continuous movement of water between the oceans, the atmosphere, and the land.

Evaporation: the process where liquid water turns into gas because of the heat from the sun.

Condensation: when water vapor cools down and turns back into liquid to form clouds.

Precipitation: water that falls from the sky to the ground as rain, snow, or hail.

Groundwater: water that is located under the Earth's surface, often stored in aquifers.

Ocean: a very large body of salt water that separates the continents.

Sea: a smaller area of salt water that is usually near the coast and partly surrounded by land.

Current: a continuous movement of ocean water, similar to a river flowing through the sea.

Tide: the regular rise and fall of the sea level caused by the gravity of the sun and the moon.

Wave: a movement on the surface of the water created by the wind.

Tributary: a smaller river or stream that flows into a larger main river.
