EARTH 4K VIEW

Composition: Earth is composed mainly of iron, oxygen, silicon, and magnesium, with a solid inner core and a liquid outer core primarily made of iron and nickel.

Atmosphere: The Earth's atmosphere consists mainly of nitrogen (about 78%) and oxygen (about 21%), along with trace amounts of other gases like carbon dioxide and argon.

Hydrosphere: About 70% of Earth's surface is covered by water, with the majority in the oceans. Only a small portion (about 2.5%) of Earth's water is freshwater, and much of that is locked in ice caps and glaciers.

Continents: Earth's surface is divided into seven major continents: Africa, Antarctica, Asia, Europe, North America, Australia, and South America.

Magnetosphere: Earth has a magnetic field created by the movement of molten iron in its outer core. This magnetosphere helps protect the planet from the solar wind and cosmic radiation.

Tectonic Activity: The Earth's lithosphere is divided into several large and numerous smaller tectonic plates that float on the semi-fluid asthenosphere beneath them. The movement of these plates leads to earthquakes, volcanic activity, and the formation of mountains.

Life: Earth is the only known planet to support life. It has a rich diversity of organisms, ranging from microscopic bacteria to complex plants and animals.

Moon: Earth has one natural satellite, the Moon, which plays a significant role in stabilizing its axial tilt and creating tides in the oceans.

Axial Tilt: Earth's axial tilt is approximately 23.5 degrees, which is responsible for the changing seasons as it orbits the Sun.

Ecosystems: Earth's varied ecosystems include deserts, rainforests, grasslands, oceans, and more, each with its unique flora and fauna adapted to the specific conditions.

Human Impact: Human activities have had a significant impact on Earth's environment, leading to issues like climate change, deforestation, loss of biodiversity, and pollution.
