Q3 Vocab Earth's Atmosphere and Water Cycle

Geosphere

• The rocky solid part of the earth.

• The gaseous layer surrounding the earth.

• The liquid layer of the earth's surface.

• The biological component of the earth.

Troposphere

• The layer of Earth's atmosphere where weather occurs and is closest to the ground.

• The layer of Earth's atmosphere that contains the ozone layer.

• The layer of Earth's atmosphere that is primarily composed of helium and hydrogen.

• The layer of Earth's atmosphere that is responsible for the auroras.

Infiltration

• When water on the ground surface soaks into the soil.

• The process of water evaporating from the soil surface.

• The movement of water through the atmosphere.

• The collection of water in rivers and lakes.

Precipitation

• Any form of water that falls from clouds and reaches Earth's surface (rain, snow, sleet, hail).

• Only rain that falls from clouds.

• Water vapor that condenses in the atmosphere.

• Water that evaporates from the Earth's surface.

Ozone

• A gas that absorbs ultraviolet solar radiation and is found mostly in the stratosphere.

• A solid that reflects ultraviolet solar radiation and is found mostly in the troposphere.

• A liquid that absorbs infrared radiation and is found mostly in the mesosphere.

• A gas that emits ultraviolet radiation and is found mostly in the thermosphere.

Sun

• Energy source that drives the water cycle (causes evaporation).

• A celestial body that orbits the Earth.

• A source of artificial light.

• A planet in our solar system.

Sublimation

• The process in which a solid changes directly into a gas.

• The process in which a liquid changes into a solid.

• The process in which a gas changes into a liquid.

• The process in which a solid changes into a liquid.

Condensation

• When water changes from a gas to a liquid due to loss of heat energy.

• When water evaporates from a liquid to a gas due to heat energy.

• When water freezes from a liquid to a solid due to loss of heat energy.

• When water boils from a liquid to a gas due to heat energy.

Atmosphere

• Layers of gases that surround the Earth.

• A type of weather phenomenon.

• A solid layer of minerals beneath the Earth's surface.

• The outermost layer of the Earth.

Nitrogen

• Makes up 78% of the Earth's atmosphere.

• Is a noble gas found in trace amounts in the atmosphere.

• Is the primary component of Earth's crust.

• Is essential for photosynthesis in plants.
