  1. The rust and the mantle are composed in different ways.

  2. They are convered by the oceanic crust far exceeds that of the continental crust.

  3. The inner core is solid through its temperature exceeds that of the outer and the mantle.

  4. There is huge temperature difference between the top bottom the mantle.

D Correct answer
Explanation

The enormous temperature difference between the top and bottom of the mantle creates convection currents that drive plate tectonic movement. Hotter material near the core rises, while cooler material near the crust sinks, creating circular motion that moves the plates above.

A Correct answer
Explanation

The topmost layer of the soil is called topsoil. This layer is usually fairly loose, porous, dark and rich in humus. The humus is derived from decomposed and partly decomposed organic matters of plant and animal origin in the soil. It plays important role in maintaining the fertility of the soil.

Atmosphere of the earth is held by _____________.

  1. Frictional force

  2. Reaction force

  3. Electromagnetic force

  4. Gravitational force
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D.  Gravitational Force

Earth's atmosphere is the layer of gases around the Earth. The atmosphere is held in place by Earth's gravity. It is made up of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun. It makes our days cooler and our nights warmer.

Solid particulates, including ash, dust, volcanic ash, etc. are small parts of atmosphere. They are important in making clouds and fog.
