Arrangement, Structure Layer of Planet Earth
Layers of Planet Earth - Composition, Structure, Atmosphere, Evolution, Function, Climate and Weather: Earth is home to millions of living things, including humans. Earth's mineral resources and other biosphere products contribute to the provision of resources to support the global human population.
Earth
Earth is the third planet of the Sun which is the most populous planet and the fifth largest of the eight planets in the Solar System. Earth is also the largest of the four earth planets of the Solar System. Earth is sometimes called the world or the Blue Planet.
The earth formed about 4.54 billion years ago, and life appeared on its surface in the first billion years. The Earth's biosphere then slowly changes the atmosphere and other basic physical conditions, which allows the proliferation of organisms and the formation of an ʻozone layer, which together with the Earth's magnetic field blocks harmful solar radiation and allows microscopic living things to breed safely on land. Physical properties, geological history, and Earth's orbit make it possible for life to survive.
The Earth's lithosphere is divided into a number of rigid segments, or tectonic plates, which have moved across the Earth's surface for millions of years. More than 70% of the Earth's surface is covered by water, and the rest consists of continents and islands that have many lakes and other water sources that contribute to the formation of hydrosphere.
The Earth's poles are mostly covered with ice; solid ice in Antarctic ice sheets and sea ice in polar ice packs. The interior of the Earth is still active, with the inner core consisting of solid iron, while the outer core is a liquid that creates a magnetic field, and a relatively thick thick layer in the mantle.
The Earth interacts gravity with other objects in space, especially the Sun and Moon. When circling the Sun in one orbit, the Earth rotates on its axis 366.26 times, which creates 365.26 solar days or one cider year.
The rotation of the Earth on its axis is tilted 23.4 ° from the plane of the orbit, which causes a difference in seasons on the Earth's surface with a period of one tropical year (365.24 solar days). The moon is the only natural satellite of the Earth, which began to orbit the Earth about 4.53 billion years ago. The gravitational interaction between the Moon and the Earth stimulates ocean tides, stabilizes the tilt of the axis, and gradually slows the Earth's rotation.
Earth is home to millions of living things, including humans. Earth's mineral resources and other biosphere products contribute to the provision of resources to support the global human population. The Earth region inhabited by humans is grouped into 200 sovereign states, which interact with one another through diplomacy, tourism, trade, and military action.
Lithosphere (Earth's Crust)
Is the topmost rock layer on the surface of the earth called the earth's crust. Under the continent, the thickness of the earth's crust reaches 70 km, under the ocean is only about 6 km. the temperature in the earth's crust reaches about 1,050 degrees Celsius.
