Is it because of gravity that meteriods fall to earth?
Only partially. Meteoroids passing near Earth are affected by Earth's gravity, but they are traveling far faster than escape velocity, that gravity is usually insufficient to cause an impact. Rather, meteoroids strike Earth and its atmosphere when their trajectories around the sun intersect that of Earth such that they will pass through the same place at the same time. In the case of a near-miss, Earth's gravity will alter an asteroid's or meteoroid's orbit. In some cases this change can lead to a collision later on.
What are the characteristics of the moon?
The moon has many characteristics, but which are unique? well, there are quite a few!! - craters - no atmosphere - special layers and phases - canyons and mountains - aluminum and titanium crust - there are many moons in the solar system, not just one!!
Which layer protects us from meteriods?
The Earth's atmosphere protects us from meteors. When meteors enter our atmosphere, they burn up due to the friction with air molecules, creating the streaks of light we see in the sky. Larger meteors that survive the journey through the atmosphere may impact the Earth's surface.
WHere do you find Deoxys' meteriods?
In veilstone city at the east there will be four meteorits that each have the ability to change the form of deoxys that are: (attack form), (defense form), (speed form), (normal form).
Which atomspheric layer has meteriods located in it?
Meteors are typically found in the mesosphere, which is the third layer of Earth's atmosphere. This region is where most meteoroids burn up upon entering the atmosphere due to the high temperatures and friction generated by their high-speed entry.
Where do meteriods come from?
Meteoroids are rocky or metallic fragments from space that come from comets or asteroids. They can be leftovers from the formation of the solar system and are usually small in size, ranging from dust particles to boulder-sized objects. Many meteoroids enter Earth's atmosphere as meteors and may land on the surface as meteorites.
Will neptune ever get hit by meteriods?
No. Neptune is a gas giant, which means it is made up of gas and has no solid surface. With no surface there is nothing for celestial objects to hit. Objects entering Neptune would simply get blown into orbit by the extremely fierce thousand-mile an hour winds. If the object somehow manages to break free of the winds, it will be vaporised by the molten core.

How much meteoritic material hits earth every day?
Several thousands. Most of them are the size of a grain of rice or smaller. A few each day may be the size of a baseball or occasionally the size of a basketball.Once a week or so, the Earth is hit by a rock the size of a car, and once every few months, we get hit by something the size of a house. A couple of months ago, a meteor the size of a house exploded over central Indonesia; it scared a lot of folks, but apparently did no damage.The VAST majority of these burn up completely in the atmosphere, surviving as nothing but dust. A few do make it to the Earth, often in small (fist-sized) chunks. Very few do any damage. Only a few people are known to have been hit by a meteorite; there was a boy in Germany last year who was struck in the hand by a meteorite the size of a pea.Every few hundred years, bigger things hit the Earth, and some do a lot of damage. In 1908, a meteor or small comet exploded high in the atmosphere near a place called Tunguska, Siberia, causing an explosion the size of a nuclear bomb. 5000 years ago, a meteor struck in the Indian Ocean causing a tsunami, which may be the source of the "Great Flood" legends in Gilgamesh and Noah's Ark. 14000 years ago, something hit northern Canada causing the "Younger Dryas" mini-ice age.
