The water cycle is made up of Hydrogen, Oxygen, and other minerals. The earth has hydrogen and oxygen but also carbon, nitrogen, phosphate and a lot of other minerals. They both are made up of H2O because they are both primarily water.

The water cycle has been in circulation for the entire life span of earth and a humans circulatory system is in circulation for their entire life span. People can not live with out their circulatory system and the earth can not function with out its water cycle.

The water cycle starts when the sun’s heat evaporates water from the oceans into the atmosphere and form clouds. When the conditions are right the clouds release water as rain or snow. Most of the rain falls back into the ocean but the rest is onto the land. Rivers and streams collect water from the ground and return it to the ocean and the cycle starts again. The water cycle began at the beginning of

The earth is made up of oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium, titanium, hydrogen, phosphorous, carbon, manganese, sulfur, barium, chlorine, chromium, fluorine, zirconium, nickel, strontium, and vanadium.

the earth’s development.

The earth is composed of five parts, the atmosphere, the hydrosphere, the lithosphere, mantel, and crust. The hydrosphere is made up of mostly oceans but also includes all water surfaces on the earth. The lithosphere is made up of the crust and upper mantel, they are divided into plate tectonics. The crust and mantel of the earth allow for the magma to flow which when it needs to replace old crust and magma. It is so far down in the earth because it is so hot. The core of the earth can be as high as 6650 degrees Celsius. When magma comes out of the earth is pushes the older crust aside and forms new crust .

Every layer of the skin has an important purpose to it to protect people. Our skin is made up of three important layers the epidermis, the dermas, and the papillae. The middle layer of skin is the papillae it is the reason that we have fingerprints and the bottoms of our feet have little lines on them. Each little papillae contains a blood vessel or a special nerve ending. The epidermis is the outer layer which is made up of a layer of dead cell
