Water cover of the earths surface 20 percent 30 percent 50 percent 70 percent?
Water covers about 70 percent of the Earth's surface.
What is the depth of earth surface in kilometers?
A surface has area but no depth. Therefore the Earth's Surface has a depth of 0.0 kilometers.
Where is about 90 percent of earth's atmosphere found?
The troposphere, the lowest layer of Earth's atmosphere, contains about 90% of the Earth's atmosphere. This layer extends from the Earth's surface to about 8-15 kilometers above sea level.
What occupies 29 percent of the Earth's surface?
Landmasses occupy approximately 29 percent of the Earth's surface.
What covers 27 percent of Earth's surface?
Land covers approximately 27 percent of Earth's surface. This includes continents and islands.
How much of the world's surface is made out of water?
Land covers 29.22 percent of the Earth's surface. This is about 57.5 million square miles (149 x 106 square kilometers). Water covers the other 70.78 percent of the Earth's surface. This is about 139.4 million square miles (361 x 106 square kilometers
Why do all planets with and without atmospheres collide with meteoroids?
All planets, both with and without atmospheres, encounter meteoroids. If the planet has an atmosphere then those meteoroids will burn up long before reaching the surface. Those without atmospheres do not have such protection and so the meteoroids strike the surface directly.
What is the dependent ability for elements to absorb light in stellar atmospheres?
The dependent ability for elements to absorb light in steller atmospheres is the surface temperature of the star.
What is a gas planet made out of?
Gas planets, such as Jupiter and Saturn, are primarily composed of hydrogen and helium, with smaller amounts of other gases like methane and ammonia. These planets lack a solid surface and instead have thick atmospheres that extend many thousands of kilometers into space.
Is there any atmospheres in Saturn?
Yes; Saturn is primarily "atmosphere." It doesn't have a firm surface the way Earth does.
What is the size of the Earth we live on?
The total area of the Earth is approximately 510 million square kilometers and the oceans cover about 71 percent of the Earth's surface, which is about 360 million square kilometers.. the diameter of earth is 12,756.3 kilometres
What is the surface area of the moon in square kilometers?
The moon has a surface area of about 37.93 million square kilometers.
How many kilometers is the boundary of biosphere below the earths surface and above the esrths surface?
32 kilometers
What is the surface area of Mars?
Mars' total surface area is equal to 144,798,500 km² (55,907,000 square miles). This is about 28.4 percent of the Earth's total surface area.144,798,500 km2 or roughly one third the surface area of the Earth.
Water cover of the earths surface 20 percent 30 percent 50 percent 70 percent?
