A hemisphere is one half of the sphere that makes up Earth's surface.
The Earth's surface is made up of water and land. Approximately half of the Earth's surface is covered by water bodies such as oceans, seas, lakes, and rivers, while the other half is covered by landmasses.
That depends where it is. On the surface of the planet it would be lava and in the earths core it would be the mantle.
The ratio of the distance on the map to the actual distance on the Earth's surface is called the scale of the map. It indicates how much smaller the features on the map are compared to their actual size on the ground.
The UK covers approximately 0.2% of the Earth's total surface area.
An underwater ridge rising close to the surface is called a reef. A reef is typically made of rock, sand or coral that lies 80 meters or less beneath low water.
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
To the north of the equator is the northern hemisphere, and to the south is the southern hemisphere.
