The _________ interacts with Carbon dioxide and other gases in the atmosphere that make warm (greenhouse effect). This provides warm environment which is conducive for living things. The high energy from the sun is captured by plants to make sugar and oxygen from carbon dioxide and water.

Solar Energy

The process carbon dioxide and water converted to sugar and oxygen using sunlight is referred to as __________. This is important because all living things need oxygen to survive.

photosynthesis.

The Earth life system is made up of four interconnected spheres: the ____, ____, ____, and ____.

lithosphere, hydrosphere, biosphere, atmosphere

__________ is composed of 78 % nitrogen, 21 % oxygen and small quantities of argon, carbon dioxide, and other elements. Some of the gases are taken in by plants and animals in the release of energy.

Atmosphere

This is the layer that is nearest to the Earth’s surface. It extends from the surface, up to 8-14 km high above sea level.

Troposphere

The bottom layer of the atmosphere stretches to about 11 km, temperature decreases with altitude and where weather conditions happen.

Troposphere

•the second layer of the atmosphere •up to about 50 km •with horizontal air currents •temperature increases with altitude •contains the ozone (O3) layer in the upper region •where most jet planes travel through •contains about 24% of the air

Stratosphere

•the third layer of the atmosphere •up to about 80 km •temperature decreases with altitude •the coldest layer •where most meteors burn up

Mesosphere

•the fourth layer of the atmosphere •to about 1000 km •the hottest layer (due to ions, H+ and He-, that directly absorb the sun’s radiation) •temperature increases with altitude •where radio waves are reflected

Thermosphere

•The _________ is the outermost layer of our atmosphere. •The _________ is a thin, atmosphere-like volume surrounding a planet or natural satellite. •The _________ is the uppermost region of Earth's atmosphere. •It contains mainly oxygen and hydrogen atoms

Exosphere

The thermosphere and exosphere are technically the _______ layers because they absorb the shortest wavelengths of solar radiation, heating (and also ionizing) molecules

Warmest

The _______ is the solid, outer part of Earth. The _______ includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure.

Lithosphere

The solid ground where you stand upon. It is lighter than the oceanic crust as it is composed of lower density materials such as granitic rocks. Continental crusts are formed through volcanic eruption.

Continental Crust

It is made of heavier basalt and gabbro rocks. ________ is younger than the continental crust as the oldest age for this type is around 200 million years old compared to the four billion year-old continental crust.

Oceanic Crust

_______ is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. The _______ is the combined mass of water found on, under, and above the surface of a planet, minor planet, or natural satellite.

Hydrosphere

The ________, also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth.

Biosphere
