What is the most important layer of the earth Why?
As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.
What are the three most important layer of the earth?
The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core.
Is the mantle the most important layer of the earth?
The Mantle Earth’s mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (>90%) is convected through the mantle to the base of the lithosphere.
Which layer of the Earth is most important and why?
The temperature of the troposphere decreases with an increase in height.it is very close to the earth’s surface . that’s why it is called the most important layer of the atmosphere…. hope this helps you !
Which is the most important layer of the atmosphere Why do you think it is important class 7?
Ans: Troposphere is considered as the most important layer of the atmosphere because:- A) All weather phenomena, such as, cloud, rainfall, storms etc. occur in this layer. B) The temperature of the air decreases with the increase in height at rate of 1°c for every 165 m, which is known as normal lapse rate.
What is the importance of the three layers of the Earth?
Explanation: We have the inner core, outer core, mantle and crust which play an important role on Earth. The layers of the Earth are responsible for the formation of our continents.
What are the 3 layers of the Earth describe each?
The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite….The core.

What are the two most important things about the mantle?
Most kimberlites surfaced long ago. The two most important things about the mantle are as follows: It is made of semi-solid rock. It is hot.
What is the importance of mantle convection?
This flow, called mantle convection, is an important method of heat transport within the Earth. Mantle convection is the driving mechanism for plate tectonics, which is the process ultimately responsible for producing earthquakes, mountain ranges, and volcanos on Earth.
Which layer is the most important layer for biological activity?
Solution(By Examveda Team) Troposphere plays important role in moderating the temperature on earth that makes it habitable. This delicate exchange of energy between the earth’s surface and atmosphere forbids the earth from becoming too hot and too cold.
Which layer of the earth is most important and why?
How is stratosphere a very important layer of atmosphere?
The stratosphere is where you’ll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn’t be possible without this layer of protection.
