Why is Earth the only planet with life?
What makes the Earth habitable.
It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon..
How was earth named?
The name “Earth” is derived from both English and German words, ‘eor(th)e/ertha’ and ‘erde’, respectively, which mean ground. … One interesting fact about its name: Earth is the only planet that wasn’t named after a Greek or Roman god or goddess.

Hence, it is neither too cold nor too hot. … The earth is a watery planet with 70% of the earth’s surface covered by water.It has an atmosphere which receives heat from the sun by solar radiation and loses heat by earth’s radiation.Jun 13, 2018
What are two of Earth’s surface features?
Mountain ranges, subduction trenches, tectonic plates, and mid-ocean ridges are all visible in the image. The Earth’s surface is composed of rigid plates that move relative to each other. The plates have three main motions, and each one has different results.
Why Earth is called a unique planet?
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 are the 7 layers of earth?
If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core. However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core.
What are the three surfaces of the earth?
Today the outline of Africo-Eurasia is well established and the entire area is recognized as the largest land mass-not as three continents. Simply stated the earth’s surface is covered with water, land and ice.
What are the major features of earth?

What is the oldest name for Earth?
TerraTerra is the Latin name for Earth and was used by the ancient Romans meaning basically the same as Gaia for the Greeks.
What will happen if the Earth is bigger than its current size?
First, if the Earth is bigger that its current size, it would also gain a stronger magnetic field and greater gravitational pull because of the additional mass, and this is a bad news for us, because lifting an object would be so much difficult than ever before due to the increased pull of gravity.
What are the 3 main features of the earth?
The three main features of the Earth are the land, the water and the air. Land areas include the seven continents and other landmasses.
What are Earth’s surface features?
– Surface features are landforms and bodies of. water that cover the Earth’s surface such as: • mountains. • valleys. • canyons.
