What do you know about the Earth's Systems?

• I got nothing.

• a little bit, we talked about a couple of them, right?

• I know all kinds of stuff!

The atmosphere is the envelope of gases surrounding a celestial body, such as a planet or moon. On Earth, the atmosphere is composed mainly of nitrogen (about 78%), oxygen (about 21%), and trace amounts of other gases such as carbon dioxide, water vapor, and noble gases.

Atmosphere

The hydrosphere refers to the total amount of water on a planet, including all forms of water such as liquid, solid (ice), and gas (water vapor). On Earth, the hydrosphere encompasses all bodies of water, from oceans, seas, and lakes to rivers, groundwater, and glaciers.

Hydrosphere

The geosphere refers to the solid components of the Earth, including the rocks, minerals, and the layers that make up the Earth's interior. It is composed of the crust, mantle, and core.

Geosphere

The zone of life on Earth, which includes all living organisms and their interactions with the various components of the Earth system such as the atmosphere, hydrosphere, and lithosphere. It is the sum total of all ecosystems on our planet.

Biosphere

Geosphere

The "skeleton" on the planet

The Geopsphere contains the crust, lithosphere and all rock material on the planet. The tectonic interactions on the planet (volcanos, earthquakes, etc) are also part of the geosphere. If its non living, it's part of the geosphere.

Remember, the lithosphere is the upper most layer of the Earth. Its where we see the nonliving part of what's happening in the mantle and core.

The Earth's Layers

Tectonic activity in the mantle and lithosphere takes molten matter and ejects it onto the earth's surface.

Plate Tectonics

Rocks, sand, soil, are the nonliving result of the tectonic activity and the visual proof that the geosphere exists.

Rocks

Biosphere

All the living stuff

The Biosphere consists of all the living organisms on the planet, be they plant, animal, fungi, bacteria, or other cellular organisms. The biosphere overlaps with the hydrosphere and the atmosphere because some living organisms spend their time in those two places (think fish and birds).

Fungi, protists, and bacteria are all different types of microorganisms.They're found just about everywhere on the planet

Fungi, Protists, Bacteria

Plants are living organisms that belong to the kingdom Plantae. They are multicellular, photosynthetic eukaryotes that play a vital role in the ecosystem.

Plants

Living organisms that belong to the kingdom Animalia. They are multicellular, eukaryotic organisms that are characterized by their ability to move, consume organic material, and reproduce sexually

The Water Cycle

Water, Water, Everywhere!

The water cycle, also known as the hydrological cycle, is the continuous movement of water on, above, and below the Earth's surface. It involves the processes of evaporation, condensation, precipitation, and runoff.

The Carbon Cycle

Carbon Dioxide affects Climate

the process by which carbon is exchanged between the atmosphere, land, oceans, and living organisms. It plays a crucial role in regulating Earth's climate and is essential for sustaining life on our planet.

The Nitrogen Cycle

Why Farts are important (seriously)

The nitrogen cycle is a vital biogeochemical cycle that describes the movement and transformation of nitrogen in various forms within ecosystems. Nitrogen is an essential element for all living organisms, as it is a key component of amino acids, proteins, and nucleic acids (DNA and RNA).
