What is the biosphere why Earth is called as a unique planet explain?

Earth is the only known planet of the solar system which supports life. Earth has oxygen, water and temperature. All these conditions which are supporting life, like presence of water and air in a good proportion, presence of life supporting gas and balanced temperature make earth a unique planet.

What makes the Earth unique from the other planets?

Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun’s rays. The fact that Earth hosts not just life, but intelligent life, makes it doubly unique.

What is biosphere How does it make Earth unique Why do you think the biosphere would be affected if there is a break in the water cycle?

Biosphere is the life supporting zone of the earth where the atmosphere, hydrosphere and lithosphere interact and together make life possible. Biosphere will be affected if there is a break in the water cycle because such a break will cause disruptions in the amount of rainfall and precipitation.

How does the biosphere depend on the atmosphere and hydrosphere to survive?

For instance, plants (biosphere) grow in the ground (geosphere), but to survive they absorb water (hydrosphere) and carbon dioxide (atmosphere). Nor are plants merely absorbing: they also give back oxygen to the atmosphere, and by providing nutrition to animals, they contribute to the biosphere.

What makes the Earth a unique planet Class 8?

Conditions favourable to supporting life are only to be found on earth. The earth is neither too hot nor too cold. There are water and air in it, which are very important for our survival.

What makes the Earth a special planet for Class 3?

The earth is at the right distance from the sun and has right mixture of air, heat and water which makes life possible on earth. It is the only planet where life is known to exist. Existence of life on earth makes it unique planet in the solar system. …

Why is the biosphere very important for the existence of human beings?

The biosphere is important for the survival of human life because it is the zone of the earth where air, land, water and other biotic and abiotic elements interact with each other to support life.

What makes the biosphere as the earth’s integrated life supporting system?

The Earth’s water—on the surface, in the ground, and in the air—makes up the hydrosphere. Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these spheres.

How does biosphere depends on the atmosphere to survive?

In more subtle ways, atmosphere-biosphere interactions influence the health of the air we breathe (see figure): rough surfaces of vegetation remove aerosols, ozone, and other reactive gases from the air through dry deposition; plants emit a huge variety of volatile organic compounds (VOCs) that are precursors to …

How is the biosphere connected to the atmosphere?

The interaction between the biosphere and the atmosphere affects all living organisms, including humans. From atmospheric transport and deposition of heavy metals to the effects of ground-level ozone on forested ecosystems, the biosphere and atmosphere are inextricably linked.

What is the Earth called unique planet?

The earth is called a unique planet because: It is the only planet which has favorable conditions that support life. It is neither too hot nor too cold. It has water and air, which are very essential for our survival.

How can you say that our Earth is a unique planet in the solar system?

The ability of the Earth to harbor life makes the Earth a unique planet in the solar system, and this stems from the fact that water in liquid form exists on the planet. Similarly, the existence of gaseous oxygen in the atmosphere of the Earth also supports life.

Why is the biosphere unique to Earth?

The biosphere is unique to Earth because it’s the only planet known to support life. It’s believed that Earth’s biosphere started about 3.5 to 4.1 billion years ago. All living things originated from a common ancestor called the last universal common ancestor (LUCA).

What makes Earth unique in the Solar System?

What Makes Earth A Unique Planet In The Solar System? The presence of life forms makes Earth a unique planet. In the solar system, the Earth is the third planet from the sun, and it is the only planet known to have life.

What makes life possible on Earth?

What Makes Life Possible on Unique Planet Earth? 1 Earth has water. Water is the basic need for living organisms to survive. Earth is the only planet that has life on it, and water content is one of 2 Energy sources on earth. 3 Plate Tectonics only available on earth. 4 Earth is rich in minerals. 5 Distance from the Sun.

How does the biosphere interact with the other spheres?

The biosphere constantly interacts with Earth’s spheres. For example, living things pull water from the soil and air. And oceans soak up carbon from the air. Finally, specific bacteria from the biosphere are only capable of building certain types of rocks. Where is the biosphere on Earth?
