Characteristics Of The Earth :Which Made It A Planet Suitable For Life

The Earth : is the only place I knew life in the solar system, is home to millions of living organisms, and its nearby sphere flounder; after the Earth the Sun about 150 million km, the Earth's orbit around the Sun makes their temperatures suited to the emergence and continuation of life, plus the appropriate size of the globe making it retains its atmosphere and water, and the presence of ozone that protects organisms from these rays damage.

Characteristics that have made the earth suitable for life

 The chemical composition of the Earth

It consists of chemical elements such as iron, oxygen, silicon, and magnesium, sulfur and aluminum, as elements heavier ones gravitate toward the center, and lighter ones gravitate toward the so-called separation between the stars, it has pointed geochemistry scientists, that more than 47% of the earth's crust is made up of oxygen, the earth's crust and which consists of rocky ingredients is a different oxides, and states that mineral elements in volcanic rocks consist of basic oxides, ammonia, silica and iron.

 Lithosphere

 Lithosphere: which is so hard cover that surrounds the globe and is based on the interior, composed of thick layers and covered about mostly soil resulting from the fragmentation that has occurred to many of those rocks, and vary the terrain on the surface of the earth from one place to another, and the lithosphere component of the Earth's surface may exposure over the long years of operations due to geological factors and tectonic erosion.

Hydrosphere to surface water: is the main cause of this planet from other planets, it is worth mentioning that the Earth's hydrosphere consists of bodies of water, such as oceans, seas, rivers, and groundwater, so changes in Earth's climate related changes of temperatures in these bodies of water as the Southern Oscillation phenomenon.

Atmosphere atmospheric: consists of basic elements: oxygen, nitrogen, allowing the existence of life on Earth, the existence of Amazon layer that work to block out UV rays from reaching the Earth's surface, as the importance of the atmosphere it is founded on providing gases that work on burning Meteors before colliding with the Earth's surface, and adjust the temperature and water vapor moves into the upper layers of the rain, so it helps in locking up the thermal energy in the Earth, and is divided into the upper atmosphere to Layers: the stratosphere mesosphere, and  thermosphere , each layer of the layers have special properties.

Biosphere: is the foundation in the power to live on this planet, and is divided into dynamic environments that live on plants and animals, where the line between these environments and high-latitude land from the sea level.

 Natural resources: where available on the surface of the land needed for the life of the resources. Some of these resources are renewable, such as mineral fuels, and some are renewed, as it provides vital products for humans; such as food, wood, oxygen and others, so the environmental system is located on the surface of the earth depends on the soil, clean water, human lives through the use of raw materials.
