The Effect Of Height Of A Crater On Its Diameter

In the movie when the crew was on the crater drilling, nothing was coming out of the hole. When there is drilling taking place the rock or dirt needs to be displaced into the surrounding area. In the movie nothing came out of the hole during the entire drilling process. There was almost no gravity on the asteroid to be able to hold the remnants and dust in the hole being drilled.

The first factor that must be considered is the viscosity of the magma. This can determine how powerful an eruption is and what shape the volcano

One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes sides are of a steep gradient then the

Some important factors that affect the size of the crater are, the weight of the marble, the size and shape of the marble, the depth and type of sand, the material of the marble and the speed at which the marble is thrown.

One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes sides are of a steep gradient then the lava from the volcano would flow must faster than if the sides were a steady gradient. Mount Nyiragongo for

About 7,700 years ago, Mount Mazama erupted on itself after building upon itself and reaching an impressive height of 12,000 feet. The aftermath of the collapse left a crater more than 2000 feet deep and 6 miles wide (Reichmann)! The rocks and minerals from the Mount Mazama

In 1975, two scientists by the name of Dr. William K. Hartmann and Dr. Donald R. Davis, came up with a groundbreaking new theory on how the moon was created. Their theory stated “At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth 's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon” (Hartmann & Herres 1). This theory is known as the Giant Impact Theory and is the accepted theory in the scientific community of how the moon was created. Even though this theory is accepted by most, there are still some people who don’t hold this theory to be true. I agree with Davis and Hartmann’s Giant Impact Theory that a great collision occurred and created the moon. The Giant Impact Theory is supported by the lack of iron on the moon, the moon rocks from the Apollo missions, and its acceptance in the scientific community.

Hypothesis: No the size of the crater and ejecta will change because it will have lighter and harder impacts on the surface.

The Giant Impact theory is one of the most best described theory of the formation of the moon. The theory is very accurate and is best fit for how the moon was formed. The Giant impact theory is the theory that is more logically correct because of a few reasons; one is the theory has more scientific evidence collected for it than other theories, this theory is more logical in science and mathematics, and this theory is more in detail on the forming of the moon. The Giant Impact theory should be the number one theory for the formation of the moon in science.

There are two types of craters, simple and complex. Craters are formed when a projectile comes at a fast speed and has a large mass. After hitting the ground the objects impact immediately creates a shock wave. Wave release and material flow will usually make the crater bigger. Rarefaction (wave release) sends impact in the air around the surface of where the projectile landed. The heat from the projectile will make the hole seep even deeper depending on where it feel. If the object feels from outer space then it’s most likely going to carry heat.

Jupiter’s moons have many different terrains which include craters on some but not on others. There are no impact craters on Io because of the active volcanoes and the lava smooths out the surface where the impact craters hit (p.241). Europa doesn't have impact craters because of the plate tectonic motion that shifts the surface with the icy terrain (p.243). Ganymede’s history was thought to have tectonics like Europa but it doesn’t seem to happen anymore because it is frozen solid (p.243). Callisto has been shown to never have tectonic activity never began there. (p.245)

The most damage is actually caused by a shock wave that is produced from a meteor that breaks apart in Earth’s atmosphere. In 2013, the Chelyabinsk meteor broke apart around 15 miles above the ground and created a shockwave that is equivalent to a 500-kiloton explosion and it injured around 1,600 people. Unfortunately, astronomers cannot predict meteorite impacts because they are too small to detect and the large ones that can be seen are too unpredictable. Meteoroids that are made of stronger materials like that of an asteroid and meteors approaching Earth slowly are the ones that usually have a better chance of impacting the ground. Luckily, around 90 to 95 percent of meteors never reach the ground. One interesting thing is that, Earth has actually seen meteorites from the moon and Mars. Impacts from meteoroids on the surface of the moon and Mars have sent chunks of the surface flying into space and eventually some of them find their way to Earth. When meteorites are not causing damage or harming people, they do provide a beautiful light show and they provide scientists with an opportunity to study the composition of comets, asteroids, the moon, and

How exactly the asteroid damaged the Earth remains unclear, but the power released by such an impact is unquestionable. Effects possibly include reduced sunlight over a period of several months which possibly led to the decline or even total halt of primary production (via photosynthesis). One of the dominant signatures of the extinction at the KT boundary was the low activity of primary production, the possibility of reduced sunlight is high (Schulte et al. 2010) . Even if the primary production proved to be on a decline when this impact occurred, there is still some uncertainties as to where exactly the impact hit. This was why asymmetries in subsurface features of the Chicxulub crater were observed via geophysical methods were analyzed and it was calculated from estimates that the
