That depends on what you mean by the "first" layer. The lowest layer (the first off the ground) is the Troposphere. The highest layer (the first coming in from space) is the Exosphere.
the layer above the earth is the troposphere
The epicenter of an earthquake is directly above the focus or hypocenter, which is the point where the seismic waves originate within the Earth. It is typically located on the Earth's surface directly vertically above the focus.
The atmosphere of Earth is held in place by gravity. Gravity pulls air molecules towards Earth's surface, creating atmospheric pressure that keeps the atmosphere from floating away into space.
The troposphere is closest to Earth's surface. It is the lowest layer of Earth's atmosphere, extending from the surface up to about 10-15 kilometers. The stratosphere is located above the troposphere.
The English term 'hydrosphere' means the watery layer of the earth's surface; the waters of the earth's surface as distinguished from those of the lithosphere and the atmosphere. Hydrosphere also means the water vapor in the earth's atmosphere.
The atmosphere extends about 600 kilometers (373 miles) above the Earth's surface.
The center of mass of Earth is located beneath the surface of the Earth, about 4,671 kilometers (2,900 miles) away from its surface. This means it is not within the atmosphere, which extends only a few hundred kilometers above the Earth's surface.
When a meteoroid is 75 km above earth's surface, it is within the troposphere.
The atmosphere extends about 62 miles (100 kilometers) above Earth's surface.
It extends to 600-700 km above earth's surface
No, the Earth's atmosphere extends much higher than 1 kilometer above its surface. The exosphere, the outermost layer of the atmosphere, extends up to 10,000 kilometers above the Earth's surface.
Earth's atmosphere extends up to about 560 kilometers (350 miles) above the Earth's surface. The outermost layer, called the exosphere, gradually transitions into outer space.
Surface of earth is in the troposphere range. The troposphere is the nearest layer to the earth.
Because it just does.
Oxygen in the Earth's atmosphere reaches up to about 100 kilometers above the surface.
Space stations, like the International Space Station (ISS), orbit within the thermosphere of the Earth's atmosphere, typically between 330 and 435 km above the Earth's surface. The exosphere is the outermost layer of Earth's atmosphere, starting at about 700 km above the surface and extending to thousands of kilometers. So, space stations do not orbit within the exosphere but within the thermosphere.
The troposphere, the lowest layer of Earth's atmosphere, contains about 90% of the Earth's atmosphere. This layer extends from the Earth's surface to about 8-15 kilometers above sea level.
