A crater is a bowl-shaped depression, or hollowed-out area, produced by the impact of a meteorite, volcanic activity, or an explosion.

Notice how the marbles make craters in the pan. The soil below the surface ( white flour ) is brought to the surface. Drop the impact object from this height and use the stopwatch to time the descent. The stopwatch must be stopped once the impact object has hit the flour/cocoa. d) how do the diameters of the craters compare to the diameters of the impact objects? Are they bigger/smaller/same size? After carrying out the above activity, hand each student a worksheet. Ask them to answer and discuss the questions provided. Many impact craters are found on the Earth’s surface, although they can be harder to detect. One of the best-known craters on Earth is Meteor Crater, near Winslow, Arizona. The crater was created instantly when a 50-meter (164-foot), 150,000-ton meteorite slammed into the desert about 50,000 years ago. MeteorCrater is 1.2 kilometers (0.75 miles) in diameter and 175 meters (575 feet) deep.The angle at which a ball enters the sand is exponentially linked with the length of the crater produced (for angles above 25 deg.). Revolutions in computing Find out how scientists are exploiting digital technologies to understand online behaviour and drive research progress NASA/JPL Deep impacts. Two teams found they could learn about the formation of lunar craters (above) by making their own craters in the lab. They dropped balls into sand and other granular materials. × Artificial intelligence Explore the ways in which today’s world relies on AI, and ponder how this technology might shape the world of tomorrow a) how did the size of the impact object affect the size of the crater? How did it affect the ejecta rays?

A crater is a bowl-shaped depression formed by the impact of a meteorite, volcanic activity, or an explosion. What you need for a crater experiment Other factors, such as the height dropped, and the diameters of the balls, were simply determined by the equipment available in the lab. Measuring large heights was impractical with metre rules, and only a certain number of balls were available at a good range of diameters.Remove the impact object and measure the crater diameter and ejecta ray diameter. Make a note of these values on your spreadsheet. The pressurised suits severely restricted movement, and due to their helmet's visors they struggled to even see their feet. Note that the 6 scaling laws in Horedt & Neukem show power-law of the diameter-energy relationships of slightly less than the 1/3 mark, most hovering around 0.28. Figure 1 from the paper, reproduced below, shows a plot of crater diameter versus impactor mass for the 6 different equations at a constant velocity (10 km/s) for solid-solid (solid lines) and ice-ice impacts (dashed lines). We can now fairly accurately determine that ball number one travelled 24 yards, and ball number two travelled 40 yards," says Cheshire-based Saunders, who has been working with the United States Golf Association (USGA) external-link to mark the anniversary. Apart from this one result, the graph clearly shows a linear relationship between the height dropped and the resulting impact crater.
