The Earth's mantle.
The layers between the Earth's surface and its center include the crust, mantle, outer core, and inner core. The crust is the Earth's outer solid shell, followed by the mantle, which is a semi-solid layer made of rock. The outer core is a liquid layer of iron and nickel, while the inner core is a solid metallic sphere at the very center of the Earth.
No country is directly in the middle of the earth. The center of the earth is made up of molten iron and nickel about 6,400 kilometers beneath the Earth's surface.
One third of the Earth's surface consists of land, while the remaining two-thirds is covered by water. This division creates a balance between terrestrial and aquatic environments, supporting a diverse range of ecosystems and habitats.
The focus of an earthquake is the point in the earth where the earthquake rupture or fault movement actually occurred. The point on the surface directly above the focus is known as the epicenter.
scale of the map. The scale of a map can be represented as a ratio, such as 1:10,000, indicating how much the distances on the map are reduced from the actual distances on the 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.
Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.
Gravity: The attraction between an object on the surface and the center of the earth.
National Center for Earth-surface Dynamics was created in 2002.
3,320kil
-- the mass of the object -- the distance between the object and the earth's center (or the object's height off the surface)
Every so-called "great circle" is (more or less) the longest circumference of the Earth that includes any two points. The great circle includes the shortest distance between the two points for travel along the Earth's surface.
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
7,000 km
As you travel from the surface to the center of the Earth, pressure will increase enormously, because of the increasing weight of what is above you.
The average distance from Earth's surface at the equator its center is about 6378 km. The distance from near the north and south poles to the center is somewhat less.
The earth is an regular surface in average with a great number of small irregularities (small with respect to the global earth surface). The geometrical center of earth is obtained by approximating the earth surface with the best fitting rotational ellipsoid, with a circular section corresponding to the equator and a minor axis joining the geographical poles. The so called "sea level" is defined as the average distance from the geometrical center of earth of all the points on the sea surface. The altitude of a single earth point is the difference between the distance from the earth center of that point and the conventional sea level.
No. The surface of the Earth is the outermost part, the part where we live. The center of Earth is the core, the middle of the sphere.
