on the Moon are caused by asteroids and meteorites colliding with the lunar surface. ... Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies. It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.

Also be, what are the three main stages of crater formation? For simplicity, we can split the formation of a crater into 3 stages: contact and compression, excavation, and modification.

What are craters ks2?

Impact craters are round, hollow areas in the ground that are made when large rocks from space, called meteorites, smash into Earth. ... This is because most craters are very old and have been worn down or buried under rocks and soil since they were made thousands or millions of years ago.

Does the earth have craters?

Earth. Liquid water, wind and other erosional forces erase impact craters on the Earth. There are still many craters on Earth which are visible from space. Some craters in areas of low rainfall (i.e. where little erosion occurs) are relatively intact, such as this crater - Meteor Crater in Arizona, U.S.A.

Does the sun have craters?

Their entire faces are mottled with spots and rashes, blotches and blemishes. But there is a big difference. On the moon the pitted craters, wrinkles and ridges are permanent scars, older than the geographical features of the earth. The spots and blemishes on the radiant face of the sun chance from moment to moment.

Why do meteors land in craters?

The meteors want the craters to be filled, so the earth can be smoother. The craters you see are the ones that have yet to be filled yet, all the others are all full so that it looks like nothing happened. The moon has more craters because it's smaller and not as many meteors hit the moon compared to earth.

Does the Moon protect the Earth?

The Moon's presence helps stabilize our planet's wobble and moderate our climate. The Moon's distance from Earth is about 240,000 miles (385,000km). The Moon has a very thin atmosphere called an exosphere. The Moon's surface is cratered and pitted from comet and asteroid impacts.

What crashed into the Moon 2020?

HELSINKI — The Chang'e-5 ascent vehicle which carried precious samples into lunar orbit was commanded to crash into the moon Dec. 7 after completing its role in the mission.

What if an asteroid hit the sun?

Nothing will happen. The mass and the heat of the Sun are of such magnitude that even the biggest object in the solar system, Jupiter, hitting the Sun would cause just a momentary hiccup, and comets are actually tiny objects in the scale of the solar system.

How big was meteor that killed dinosaurs?

Known as the Chicxulub impactor, this large object has an estimated width of 6 miles (9.6 kilometers) and produced a crater in Mexico's Yucatan peninsula that spans 90 miles (145 kilometers).

What is craters for kids?

Impact craters are round, hollow areas in the ground that are made when large rocks from space, called meteorites, smash into Earth. We can see only a few clear impact craters on Earth's surface today.

What can we learn from craters?

Craters are windows into the past, present and future. Lessons from impact craters have been essential to developing our understanding of the past and present of the Solar System. Scientists study craters on planets, asteroids and moons to learn about the geological history of those bodies.

Where is the crater on a volcano?

In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form.

What do craters look like?

Craters are roughly circular, excavated holes made by impact events. The circular shape is due to material flying out in all directions as a result of the explosion upon impact, not a result of the impactor having a circular shape (almost no impactors are spherical).

What did the flour represent in the making craters experiment?

Prepare the Moon's sub-surface Spread about an inch of flour into your cake pan. The flour represents the part of the Moon's crust that an impactor will pulverize and blast out.

Does Moon have water?

NASA recently announced that - for the first time - we've confirmed the water molecule, H2O, in sunlit areas of the Moon. This indicates that water is widely distributed across the lunar surface.

How many meteor craters are in the US?

According to the PASSC database, there are currently (2018) only 190 known and confirmed meteorite impact craters on the planet earth. Only 30 well evidentiated meteorite imact craters are located in the United States of America.

How did NASA find water on the moon?

NASA's Cassini spacecraft flew by the Moon in 1999, en route to Saturn. Its infrared spectrometer found water-bearing minerals at most latitudes on the Moon, with higher concentrations at the poles. The results were in stark contrast to the bone-dry Apollo samples.
