Asteroids that pass near Earth, even as close as the Moon, do not have any great effect. Their gravity is too weak to cause changes on Earth. However, they are a serious threat to life on Earth because of the possibility of a cataclysmic collision. These collisions between asteroids have occurred in the past, but over a period of many millions of years.
Asteroid Collisions
A part of an asteroid is thought to have collided with Earth 65 million years ago, throwing up atmospheric dust that killed plants and lowered temperatures. This period is associated with the death of most species of dinosaurs.
The effects of a large asteroid collision would be catastrophic. The initial impact can create massive plumes of earth and debris and generate massive tidal waves, while secondary effects can include widespread showers of falling debris (generating firestorms and above-ground detonations). Severity of all these effects (whether they are local disasters or global catastrophes) are based upon the size of the object.
Shock Wave
- Air: blast wave
- Ground: ground shock
- Water: water compression wave - tsunami
Thermal Radiation
- Flash
- Fireball
Electromagnetic Effects
- Electromagnetic pulse (EMP)
- Ionizing radiation
Debris and Aerosols
Secondary Effects
- Mass fires
- Earthquakes/landslides/volcanoes
- Dust and impact winter
- Oxygen depletion
- Gas evolution and acid rain
- Magnetic pole reversal
- Extreme weather conditions An asteroid is reputed to have crashed on earth a very long time ago, and brought about the demise of the dinosaurs. Such a happening could occur again, in our time. Luckily, most asteroids burn out in our atmosphere and don't pose a danger.

What effect does an asteroid have on the earth?
Virtually no effect, unless it strikes the Earth, in which the effects could be catastrophic.
What effect did being hit by an asteroid have on the Earth?
well it changed the earth to the earth we have today
What effect does a asteroid make when it hits earth?
your chin turns into a transoformer, then starts kicking beats.
What effect did the asteroid hitting earth have on it?
It all depends on the size of the asteroid and the speed. When an asteroid about 6 miles in diameter slammed into the Gulf of Mexico 65 million years ago, it killed off every large lifeform on Earth, including all of the dinosaurs.

Can an asteroid destroy the earth?
No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
The earth been destroyed by a asteroid?
No, if the Earth was destroyed by an asteroid we would not be living today.
Is the earth inside the asteroid belt?
Yes, the asteroid belt starts properly after the orbit of Mars.
What effect did the asteroid have 0n earth?
65 million years ago an asteroid or comet hit our planet it wiped 90 percent of the dinorsors out some still sivive to day like the crocadiles
Is a collision possible between the earth and an asteroid?
Yes, if the asteroid is captured by the Earth's gravitational pull.
Where did the asteroid hit earth?
What asteroid? There were several.
Will an asteroid will hit Earth this week?
Probably not. I haven't seen any news about an asteroid about to strike Earth.
