Because of gravity.
He used a variety of surfaces but mainly canvas.
That's because it looks mainly blue, from space. With the clouds it looks like a blue marble.The Earth is called the "blue planet" because the surface is composed mostly of water. Over 70 % of the Earth's surface is water.Water looks blue from space mainly because it reflects the blue atmosphere.However, the full explanation is quite complicated.(A clear sky in daylight looks blue from the Earth's surface, because of the way white light is scattered by the air molecules.)
For IR, visible, and UV radiation; any shiny surface will do. For acoustic radiation, any massive smooth surface will do. For em radiation, any material with a very different dielectric constant from that of air will do. For ionizing radiation, there is a lot of money to be made from this discovery. That problem is yet (mainly) to be solved.
Well the Earth is round because of gravity. Everything has gravity, even a pebble, however the force is so weak compared to earths gravity it is not effective. When bits if rock started joining together 5 and a half billion years ago, they started forming a large piece of rock. As this got over a certain size, its own gravity caused it to become a sphere, and that's how its got it's basic shape. However the earth has also been shaped by meteors hitting the surface, tectonic movement (earthquakes) and (mainly) volcanoes, which create a new surface when the lava cools down. That's a very brief explanation, sorry if it isn't good enough.
Discounting oceanic crust the largest areas of lavas are the flood basalts, mainly in Siberia and India.
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Erosion, weathering
Mainly gravity, and air resistance.
The inner planets are different from the other planets mainly because
The largest percentage of the earths surface is covered by water mainly the Oceans (about 71%).
scoria
Earth's surface is mainly covered by water, with approximately 71% of the planet's surface covered by oceans. Landmasses, including continents and islands, make up the remaining 29% of Earth's surface.
Someone who mainly rides downhill and do big jumps.
Mars has a thin atmosphere, mainly of Carbon Dioxide. Its surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
Mercury has no real atmosphere, so it's a bit like the moon in that respect. Venus has a very thick atmosphere of mainly carbon dioxide, it has a huge surface pressure of around 93 bar, around 93 time that of earths. Earths atmosphere is mainly nitrogen (79%) and oxygen (20%) with some carbon dioxide (1%) roughly speaking. Mars has a thin atmosphere, mainly carbon dioxide.
Any car that has to go uphill requires more effort than on a flat surface or downhill. Mainly because uphill is steeper (in an up direction) which also pushes against gravity.
how the hell im gon answer it an io asked u wt type uf bs is that
