It's because of the asteroid's kinetic energy. Think of it like this. Even though an asteroid can be relatively small (10 meters across), it moves at an average speed of 25 kilometers per second, or about 15.5342798 miles per second. Now, that alone might not seem like much. However, once you calculate the kinetic energy, or the collision energy in this case, you'll see why. The "average" asteroid is about 10 km across with a mass of 1.47 x 10^21 kg. So, after figuring it's kinetic energy, (1/2)mv^2, we find it has a collision energy of 9.1875x10^27 joules, equal to 109,375,000,000,000 of the atomic bombs dropped on Nagasaki.
What else can I help you with?
What is a depression in the Moon's surface caused by the impact of an asteroid or meteoroid?
The usual term is crater. Most craters are nearly circular holes surrounded by rims of ejected material. The term "impact basin" is used for the multiple-ringed structures formed by large impacts.
A large asteroid the size of the state Texas has made impact on the earth?
Armageddon
What are Mountains and basins?
A mountain is a natural, large elevation in the Earths surface. A basin is a depression in the Earths surface containing water.
Has the eath ever been hit by an astroind?
Yes, the Earth has been hit by asteroids in the past. These impacts have been responsible for mass extinction events and have left large impact craters on the Earth's surface. Fortunately, the likelihood of a large asteroid impact in the near future is low due to monitoring and detection efforts.
Will volcanic activity be changed due to a asteroid?
A significant impact to the planet from a large enough asteroid could cause volcanic eruptions.
What forms a crater when it hits the earth?
A crater is formed when a meteoroid, asteroid, or comet collides with the Earth's surface at a high velocity. The impact creates a depression in the ground, often surrounded by an elevated rim, due to the explosive force generated upon impact.
Where is a crater located?
A large depression in earth cause by impact of an asteroid or other object from space.
What causes an impact crater to form on a planets surface?
An impact crater is formed when a large meteorite or asteroid collides with the surface of a planet at high velocity. The impact releases a tremendous amount of energy, causing the ground to be excavated and displaced, leaving behind a depression. The size and depth of the crater depend on the size of the impacting object and the characteristics of the planet's surface.
What element makes up a large portion of the earths surface?
water
Is an asteroid 50 miles across?
An asteroid 50 miles across would be considered very large and potentially catastrophic if it were to impact Earth. Such a large asteroid could cause widespread destruction and have a significant impact on global climate if it were to collide with our planet.
What is the current theory for the origin of earths moons?
the giant impact hypothesis is currently the accepted theory. It basically says that a large asteroid collided with the earth, knocking debris from the earth into space. this debris then formed together over time to form the moon.
How was the Caloris Basin probably created?
The Caloris Basin on Mercury was most likely created by a massive impact from a large asteroid or meteorite early in the planet's history. The impact caused the surface to fracture and form the distinctive concentric rings seen in the basin today.
