EARTH SCI | Earth Spheres

Geosphere

It consists of all the rocks and minerals of earth, the landforms, and the crust and upper mantle. It is the foundational sphere, where all the other spheres are built upon.

Biosphere

All of the organisms that live on Earth

Hydrosphere

All of the water on Earth, including glaciers.

Atmosphere

All of the gases of the planet

Troposphere

It is the lowest layer of the atmosphere. It also has 80% of the air in the planet and is where the weather happens. Temperature decreases as altitude increases

Stratosphere

It is second lowest layer of the atmosphere where planes are flown. It also contains the ozone layer that absorbs the harmful rays. Temperature increases as altitude increases.

Mesosphere

The 3rd highest layer, the coldest layer of the atmosphere; temperature decreases as altitude increases.

Thermosphere

The 2nd highest layer of the atmosphere; where satellites are located; temperature increases as altitude increases.

Exosphere

The highest layer of the atmosphere before outer space. Temperature decreases as altitude increases.

Cryosphere

It is all of the solid water on our planet, such as glaciers, ice, snow. It reflects back the solar radiation entering our planet.
