What is the impact of meteor showers to the earth?

Impacting Earth When meteorites do hit the ground, their speed is roughly half what it was upon entry, and they blast out craters 12 to 20 times their size. Craters on Earth form much as they would on the moon or any rocky planet. Smaller objects create bowl-shaped craters.

Is a meteor or meteor fragment that impacts the Earth’s surface?

A meteorite is a fragment of spatial matter that falls to the surface of a planet. Most meteorites that fall to Earth come from the Asteroid Belt. Watch as a meteorite travels to Earth, causes an explosion, and creates an impact crater. Meteorites are space rocks that fall to Earth’s surface.

What kind of impact do space objects have on Earth?

Objects of this size produce global complications, throwing dust and other debris into the atmosphere around the planet, which can block off sunlight, cause acid rain, and ignite firestorms with the heat of reentering debris. These larger collisions also cause devastating shock waves and tsunamis.

How do you calculate the impact energy of an asteroid?

You can easily estimate the impact energy of an asteroid. You do this by calculating the kinetic energy of the asteroid just before it strikes the earth. This is equal to the impact energy. Kinetic Energy = (1/2) MV2

What is the frequency of small asteroids impacting Earth’s atmosphere?

Frequency of small asteroids roughly 1 to 20 meters in diameter impacting Earth’s atmosphere. Small objects frequently collide with Earth. There is an inverse relationship between the size of the object and the frequency of such events.

What would happen if a large asteroid hit the ocean?

If a large asteroid, one kilometer in diameter, impacts a large body of water, such as an ocean, the consequences can be just as disastrous as a ground strike. The impact would create waves hundreds of feet high which can flood and devastate coastal communities all around the world.

What happened to the asteroid that hit the Earth in 2013?

On February 15, 2013, an asteroid 20 meters in size entered the earth’s atmosphere over Russia, at a speed of about 20 kilometers per second. It exploded about 30 kilometers above the earth in a massive airburst explosion estimated to be about 20-30 times more powerful than that of the atomic bomb dropped on Hiroshima.
