The crust
Trees are called living things because they breath, they eat, and they reproduce. Very good question I must say.
The thin cool skin of Earth is called the lithosphere. It consists of the outermost layer of the Earth's crust and a portion of the upper mantle, where tectonic plates are located and move around.
The leaves of the trees absorb the carbon dioxide and release oxygen.They go in the process called photosynthesis.That's why we need to plant trees to save the mother earth.
Because it has the most trees which provides very mmuch oygen for the Earth.
The element that protects your skin from the sun is called ozone. Ozone in the Earth's stratosphere absorbs much of the sun's harmful ultraviolet (UV) radiation, preventing it from reaching the Earth's surface and causing damage to our skin.
a group of trees is called a forest of trees
A series of trees is called a line of trees or an avenue.
Just like the skin of body ,lithosphere is the thin outermost layer of earth having an average distance of 17 km only. This layer is also a storehouse of minerals and hence it is rightly called "Mineral skin"
The thin outermost layer of Earth is called the Earth's crust. It is the solid, rocky shell that covers the Earth's surface and is divided into several tectonic plates that constantly move and interact with each other.
trees give us lot of use full things. for example- rubber ,fruits,vegetables,shade ect. cutting down of trees is called DEFORESTATION. planting more trees is called AFFORESTATION. there are different kind of trees . example baniyan ,mango,apple ect. trees are the longest living organisims on earth.
