Question

The narrow band of land water and air where all kinds of life is possible is known as:
A) Atmosphere
B) Biosphere
C) Lithosphere
D) Hydrosphere

Answer 1

Hint: Earth developed as gravity pulled spinning gas and dust in to become the third planet from the Sun when the solar system settled into its present shape around 4.5 billion years ago. Earth has a central heart, a rocky mantle and a solid crust, as do its fellow terrestrial planets.

Complete answer:
It is possible to position everything in the structure of the Earth into one of four major subsystems: ground, water, living beings, or air.
The biosphere is the narrow band of land, water and air in which all types of life exist on earth. This layer stretches from heights up to 10 kilometers above sea level. It is the earth's fourth component. The biosphere is a global ecosystem that supports life, where each living thing relies on each other and the climate. In a thin layer, the biosphere spreads over the Earth's surface from a few kilometers into the atmosphere, to the deep-sea vents of the ocean depths in very cold conditions.
 The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients. Earth's environmental spheres. Earth's environment includes the atmosphere, the hydrosphere, the lithosphere, and the biosphere.
Hence the correct answer is option ‘B’.

Note: The atmosphere is composed of temperature-based layers. The troposphere, the stratosphere, the mesosphere and the thermosphere are these layers. At about 500 km above the surface of the Earth, another area is called the exosphere. Thermosphere, since it includes the warmest temperatures in the atmosphere, the thermosphere is also called the "hot layer" Until the approximate top of the thermosphere is 500 km, the temperature rises with height.
