Mavrix Crater Ball, High Density PU Bouncy ball

Product Information

This was the next idea for impact material, but once again the salt did not have enough integrity to hold its shape when a ball was removed. An old theory predicts a depth exponent of 1/4 by assuming that most of the meteorite’s energy goes into lifting grains out of the crater space.

Soon after, smaller eruptions began piling up lava and volcanic ash on the crater floor, slowly rebuilding the mountain. The event was more than a billion times more explosive than all the atomic bombs ever detonated on Earth. This will be due to the ball having more kinetic energy ( mass multiplied by velocity squared) – so more energy will be put into displacing the sand grains downward and outward. Measuring large heights was impractical with metre rules, and only a certain number of balls were available at a good range of diameters.The winding series of chasms and ridges radiating from a central area resemble a giant arachnid, not a circular crater. The crater length does indeed vary proportionally to the vertical height, but the crater depth appears to have no relationship whatsoever with the height (therefore the entry speed). It only appears to be affected by the entry angle, which determines the vertical component of the velocity. The same effect prevents you from slapping your open hand down through sand at the beach, even though it yields with a gentler push. It turned out that sand doesn’t splash like a liquid, but the resulting pits looked a lot like craters on the moon.

They are found on all the terrestrial planets (Mercury, Venus, Earth and Mars) and on many moons of the outer planets. So the two equations are "contradictory" (the 2nd probably being more accurate than the 1st) because of assumptions made in the derivation. To test this, you will use different sized, nearly spherical objects as your "meteorites," like the objects shown in Figure 2.Just as a doctor uses tools and techniques, like X-rays and stethoscopes, to look inside the human body, geoscientists explore deep inside a much bigger patient—planet Earth. You should have found that the bigger the ball, or the faster it was moving, the bigger the resulting crater would be. These activities are designed to be carried out by children working with a parent, guardian or other appropriate adult. Firstly, for the final experiment, the landing tray was not long enough to slow down balls travelling at high speed.

The Chicxulub Crater, off the Gulf of Mexico is thought to be the impact site of the meteor which wiped out or contributed greatly to the extinction of the dinosaurs at the end of the Cretaceous period 65 million years ago.Geologists were able to identify Spider as an impact crater only after looking at rocks unearthed from the feature’s central region. Even though the craters on the surface of the moon resemble holes in Swiss cheese, we know that this common myth is not true. Photo wizard Andy Saunders from the UK joined forces with the United States Golf Association (USGA) to breathe new life into classic lunar footage. Did you know the surface of the moon has millions of craters, varying from just a few metres across to hundreds of kilometres? This first experiment is a fairly simple one, however it is necessary – it will serve as a test for the equipment and methods used.
