Earth's Full Details.

Earth is the third planet from the Sun in the Solar System and is the largest of the four terrestrial planets. It is located approximately 149.6 million kilometers (93 million miles) away from the Sun and has a diameter of about 12,742 kilometers (7,918 miles). Here are some full details about Earth:

Size and Structure:

Diameter: 12,742 kilometers (7,918 miles)

Circumference: 40,075 kilometers (24,901 miles)

Surface Area: 510.1 million square kilometers (196.9 million square miles)

Volume: 1.083 billion cubic kilometers (259.9 million cubic miles)

Mass: 5.97 x 10^24 kilograms (1.316 x 10^25 pounds).

Composition:

Crust: Earth's outermost layer, composed mostly of solid rocks and minerals.

Mantle: Located beneath the crust, it is a semi-solid layer consisting of hot, dense rock.

Core: The innermost part of the Earth, divided into an outer liquid core and an inner solid core. The core is primarily composed of iron and nickel.

Atmosphere:

Earth's atmosphere is a layer of gases surrounding the planet.

Composition: Nitrogen (78%), Oxygen (21%), Argon (0.93%), Carbon Dioxide (0.04%), and trace amounts of other gases.

The atmosphere acts as a protective shield, regulating temperature and supporting life.

Hydrosphere:

Earth has a significant amount of water in its liquid form, making it unique among known celestial bodies.

Oceans: Cover about 71% of the Earth's surface and contain approximately 97% of the planet's water.

Freshwater: Includes lakes, rivers, glaciers, groundwater, and atmospheric water vapor.

Climate and Weather:

Earth's climate is influenced by factors such as latitude, atmospheric circulation, ocean currents, and topography.

Weather patterns include temperature, precipitation, wind, humidity, and atmospheric pressure.

Biodiversity:

Earth supports a wide variety of life forms, including plants, animals, fungi, and microorganisms.

Ecosystems: Earth's diverse ecosystems range from forests, grasslands, and deserts to aquatic environments like coral reefs and deep-sea habitats.

Human Population:

As of my knowledge cutoff in September 2021, the Earth's population was estimated to be over 7.9 billion people.

Population density varies across regions, with the majority of people living in urban areas.

Natural Resources:

Earth provides various natural resources, including minerals, fossil fuels, freshwater, timber, and renewable energy sources like wind and solar.

Moon:

Earth has one natural satellite, the Moon, which is the fifth-largest moon in the Solar System.

The Moon's gravitational pull causes tides on Earth and has had a significant influence on our planet's evolution.
