Earth

Earth also known as Terra is the 3rd planet from the Sun in the solar system of Sol.

History of Earth
Formation

Some 4.5 billion years ago materials in the inner solar system are pulled by gravity create the earth.

Shortly after Earth's formation a mars sized planet 10% the Earth's mass called Theia collided sending thousands of debris flying off into space, this debris will later form rings and then our moon. However the way Theia hit earth was different this time witch caused to spinning in a retrograde rotation.

After Formation

Size and Shape
The shape of Earth is a near perfect spherical ball, with an average diameter of 12,742 kilometers (7,918 mi), making it the fifth largest of the Solar System's planetary sized objects and largest among its terrestrial ones. Due to Earth's rotation its shape is bulged around the Equator and slightly flattened at the poles, resulting in a 43 kilometers (27 mi) larger diameter at the equator than at the poles.

Crust
Earth's curst is the top layer of Earth's rigid or liquid structure, at the interface with its atmosphere's. Earth can be divided into two hemispheres latitude into the polar Northern and Southern hemispheres, or by longitude into the continental Eastern and Western hemispheres. Regarding the surface distribution of land and water, Earth can be divided into an oceans-focused water hemisphere and a landmasses-focused land hemisphere.

Earth's surface is mostly water with some smaller amounts of ice. 70.8% or 139.43 million sq mi of Earth's surface consists of the interconnected ocean, making Earth, along with its vibrant hydrosphere, a water world or ocean world. The Earth's oceans are divided into 5 oceans, the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean, from largest to smallest. Earth also has many seas, lakes and rivers some of them being, Mediterranean Sea (worlds largest sea)  American Great Lakes, African Great Lakes, Saharan Great Lakes, Nile River (LONG). The ocean floor comprises abyssal plains, continental shelves, seamounts, submarine volcanoes, oceanic trenches, submarine canyons, oceanic plateaus, and a globe-spanning mid-ocean ridge system.

Earth also has two large ice caps on the north and south poles witch the ocean surface is covered by a seasonally variable amount of sea ice that often connects with polar land and ice sheets, forming polar the ice caps.

Earth's land is 29.2%, or 57.51 million sq mi of Earth's surface area. Earth's land consists of many islands around the globe, but mainly of four main continental landmasses, which are, from largest to smallest: Afro-Eurasia, America, Antarctica, and Australia. These landmasses are further broken down into continents. The terrain varies greatly from continent to continents and consists of mountain ranges, deserts, plains, plateaus, and other landforms. The elevation of the land surface varies from the low point of −1,371 ft at the Dead Sea, to a maximum altitude of 29,029 ft at the top of Mount Everest. The mean height of land above sea level is about 2,615 ft.
