(5) Describe the consequences of a 10-km asteroid striking Earth?

Expert Solution

Solution) An asteroid 10 km is massive so it is hard to slow down . So unlike small meteors it will not be slowed down much by air friction . It punches through the atmosphere like its hardly even there . When it reaches the surface , it will smack very hard that it does'nt matter if it strikes ocean or land . The impact with earth's crust will finally stop the asteroid . And the energy of impact will vaporize the asteroid and a large amount of earths crust ., creating a crater more than one hundred km across throwing all rock into air.

So during this time some of this debris will be going so fast that it will fly right out of earths atmosphere and go into orbit around the earth . Then most of the debris rains back down on earth on every part of earth heating the atmosphere thereby triggering forest fires and cooking anything that isn't sheltered underground .

So this combination of dust from impact and soot from forest fires will remain in earths atmosphere for a year or so and blocks light from sun . So due to this much of earth's plantlife on land and in sea will die . Many animals and even human race will die either in beginning or later due to lack of food and devastation of environment .

Dinosaurs extinction occured due to this .

A 10-meter diameter asteroid hitting the Earth is a 1 in 100 year event. If the Earth were hit by a 10-meter diameter asteroid sometime in 2018, how would the odds of the Earth being hit by a different 10-meter asteroid in 2019 compare to the odds of the Earth being hit by a different 10-meter asteroid in 2118? Please explain your answer

A circular rock 5 km in radius hits the earth head-on, at speed 36 km/s. The rock's density is 3 g/cm3. The earth's mass is 6*1024 kg. Treating the earth as initially stationary, calculate its final in speed due to the impact. Because of the system's trouble with small numbers, calculate the speed in μm/s -- the distance unit is the micron or micrometer, 10-6 meter. I am so confused on where to start, like is the rocks density m2...
