Question

write about natural realms of the earth
​

Answer 1

Answer:

Atmosphere

The Earth’s atmosphere is the gaseous layer that envelopes the world.

This layer mostly contains a mixture of mostly nitrogen (78%), oxygen (21%), and argon (0.9%). In addition, trace gases (carbon dioxide, nitrous oxides, methane, and ozone) account for another tenth of a percent.

Water vapor, dust particles, pollutants, and pollen also can be found in mixed into the atmosphere.

There are five mains layers in the Earth’s atmosphere:

Exosphere: 700 to 10,000 km (440 to 6,200 miles)

Thermosphere: 80 to 700 km (50 to 440 miles)

Mesosphere: 50 to 80 km (31 to 50 miles)

Stratosphere: 12 to 50 km (7 to 31 miles)

Troposphere: 0 to 12 km (0 to 7 miles)

Hydrosphere

All of the water on Earth is known collectively as the Earth’s hydrosphere. This is water found in the air, the soil, in glaciers, the oceans, rivers, lakes, and streams of the world.

Water is found in all three states on Earth which are gas, liquid, and solid.

As gas, water is found as water vapor in the atmosphere.

In liquid form water is found in streams, rivers, lakes, ponds, and oceans along with mist in the air and as dew on the surface of the ground.

Water is found in solid form as ice and snow.

Lithosphere

The lithosphere contains the elements of the Earth crust and part of the upper mantle. This is the hard and rigid outer layer of the Earth. The term is taken from the Greek word lithos meaning “rocky”. This part of the Earth includes soil.

Biosphere

The biosphere covers all living organisms on Earth.

There is an estimated 20 million to 100 millions different species in the world organized into the 100 phyla that make up the five kingdoms of life forms.

These organisms can be found in almost all parts of the geosphere. There are organisms in the air, soil, and water on Earth.

Answer 2

Answer:

There are four natural realms of the earth. These are

1. Lithosphere
2. LithosphereHydrosphere
3. LithosphereHydrosphere Biosphere
4. LithosphereHydrosphere Biosphere Atmosphere

Explanation:

Realm - Domain or area into which earth is divided.

Lithosphere: The lithosphere is the region of land. The term lithosphere is derived from the Greek word lithos, which meaning "rock." It is the earth's exterior solid layer, made up of rocks and soils.

Hydrosphere: The hydrosphere is the region of water. 71% of the earth's surface is covered by this layer.

Biosphere: The biosphere is the limited zone where land, sea, and air come together. It is the earth's fourth domain, and it sustains life.

Atmosphere: The atmosphere is the gaseous envelope that surrounds the Earth and extends up to 10,000 kilometres above its surface. The troposphere, stratosphere, mesosphere, and ionosphere are the bottom four levels of the atmosphere.
