Question

The atmosphere is held to the earth by
1. Gravity
2. The sun
3. Clouds
4. none of these

Answer 1

Correct Answer - Option 1 : Gravity

The correct answer is Gravity.

• The various atom of gases present in the earth atmosphere has masses and a gravitational force acts between theses atoms and earth. also, this is the force that holds the various gases near the surface and atmosphere is present.
• The magnetic field of Earth, also known as the geomagnetic field, is a magnetic field that stretches from inside the Earth to space, where it interacts with the solar wind, a stream of charged particles originating from the Sun.
  • ​The Earth's magnetic field is caused by the currents of energy owing through the molten core. These currents are hundreds of miles wide and flow thousands of miles per hour as the earth rotates. The strong magnetic field passes through the center of the earth, passes through the crust, and reaches space.
• The world, because of gravity, pulls all objects into itself. In reality, the air around our planet is kept around by gravity, and the envelope of air around the planet is called the atmosphere
• In order to solve this problem, we need to know that The atmosphere can not be protected by air, clouds, or earth magnetic fields unless and until there is an irresistible force against the surface and that force is the only force of gravitation.

• The sun is by far the largest object in our solar system. It contains 99.8 percent of the solar system’s mass and is a hot ball of glowing gases.
  • ​The gravity of the Sun holds the Solar system together keeping everything in its orbit. Planets orbit the sun in oval-shaped paths called ellipses, with the sun slightly off-center of each ellipse. Without the Sun’s energy, there will be no life on earth. 
• Cloud is a mass of minute water droplets or tiny crystals of ice formed by the condensation of the water vapor in free air at considerable elevations. As the clouds are formed at some height over the surface of the earth, they take various shapes. 
• According to their height, expanse, density, and transparency or opaqueness clouds are grouped under four types:
  • cirrus
  • cumulus
  • stratus
  • nimbus
