What layer of the Earth where the living organisms dwell in?
The thin layer of the Earth’s surface where living things are able to survive is called the biosphere. It is about 20km thick, from the bottom of the oceans high up into the atmosphere. Physical conditions outside the biosphere are too extreme to support life.

What are the layers of gases surrounding Earth called?
An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
What is the outermost sphere?
The Lithosphere. The lithosphere, sometimes called the geosphere, refers to all of the rocks of the earth. It includes the planet’s mantle and crust, the two outermost layers.
What is biosphere in environmental science?
biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.
What layer of the earth makes up the lithosphere?
The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
Which is the thin layer of gases?
the atmosphere
The thin layer of gas surrounding the earth is called the atmosphere.
How does the upper atmosphere protect living things?
Ozone in the upper atmosphere absorbs high-energy ultraviolet (UV) radiation coming from the Sun. This protects living things on Earth’s surface from the Sun’s most harmful rays. Without ozone for protection, only the simplest life forms would be able to live on Earth. MODERATES EARTH’S TEMPERATURE
What makes up the outermost layer of the Earth?
Most of the geologist believes that as the Earth cooled, the heavier and the denser material sank into the centre, and the lighter ones rose towards the top. Due to this, the outermost layer is made of the lightest materials such as rocks and granites and the innermost layer consists of nickel and iron.
Which is the second layer of the atmosphere?
ozone layer. Encyclopedic entry. The ozone layer is one layer of the stratosphere, the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. The ozone layer is one layer of the stratosphere, the second layer of the Earth’s atmosphere.
Which is the hottest layer of the Earth?
The Inner Core It is the centre and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel with temperature up to 5,500oC. Due to its immense heat energy, the inner core is more like the engine room of the Earth.
