Every year 5,200 tons (4,700 metric tons) of interplanetary dust particles reach the Earth's surface The scientists estimated that a total of 15,000 tons (13,600 metric tons) of cosmic dust rains down on the Earth annually, though most of the material is lost on entry as...Since the Earth was formed more than four billion years ago, asteroids and comets have routinely slammed into the planet. The most dangerous asteroids are extremely rare, according to NASA. An asteroid capable of global disaster would have to be more than a quarter-mile wide.Quite a few mountains ranges can be seen from space, but perhaps the most impressive are the Himalayas. It covers about 75% of Nepal, and gets its name from Sanskrit: hima means snow Everest has a couple of different names - in Nepali it's Sagarmatha, and in Tibetan it's called Chomolungma.The fastest revolving planet around the sun (a) Earth (b) Mars (c) Jupiter (d) Saturn.

Centuries ago, when astronomers had not yet accepted the idea that things fell from space into Earth's atmosphere, these "things" were thought to be stones that formed in the air.We've found atoms and molecules that remain gravitationally bound to Earth at altitudes up to 10 If we didn't periodically boost these spacecrafts, many of them would have crashed back down onto Earth already. And when large satellites do this, they make what we call an uncontrolled re-entry.A rock found on Earth that crashed down from space is called _. a meteorite. What type of stresses broke Earth's lithosphere into plates? Ultraviolet light split the water molecules, and the hydrogen then escaped to space. Why do the jovian planet interiors differ?

The word "meteor" comes from a Greek word meaning "high up" and can represent anything (or any event) that goes on, high in the atmosphere (as opposed to space).

The science of "meteorology" is the study of events that happen high in the atmosphere and, in that field of study, typical "meteors" are clouds, rain, snow...

In astronomy, a "meteor" is the streak of light that is caused when an object from space enters the Earth's atmosphere at very high speed. Unofficially, you could call that a "shooting star" even though it is not a star (not even in the ancient Greek meaning of the word "aster") and no one is shooting it.

If a piece survives to the ground, it becomes a "mineral in the ground" and gets the suffix "-ite". Thus it is called a meteorite.

Centuries ago, when astronomers had not yet accepted the idea that things fell from space into Earth's atmosphere, these "things" were thought to be stones that formed in the air.

Aeroliths

Aero = air

lith = stone

So if you read an old book (or hear an old-timer like me) talk of an aerolith, it is the same thing as a meteorite.

If you could spot the object before it hits the atmosphere and becomes a meteor, then you would call it a "meteoroid". If it is big enough (usually more than 5 metres or 15 feet across) you would then call it an "asteroid".

Both the "-oids" are still in space.

If, after the asteroid enter the atmosphere and displays a meteor, the meteorite arrives on the ground fast enough to cause some damage (however small or big) then that is an "impact" (the event of hitting) and the resulting damage, if it creates a large circle for example, would be called an "impact crater".
