What evidence is there to prove that dinosaurs became extinct?
It is a popular BELIEF that a meteorite killed the dinosaurs. There is no hard evidence to support it, and as such, your guess is as good as anyone elses. There are several craters on the planet large enough to support the theory, but the evidence is considerably lacking past that. Another popular theory is that they simply died out through the process of self extinction. They consumed all available resources, died out slowly, and eventually went extinct.

Could mass extiction have been caused by an asteroid?
It has been speculated that the mass extinction of dinosaurs was caused by an asteriod, however there is not enough evidence collected to support this. It is still argued possible though.
What is the process on earth that has wiped away evidence of impact craters?
Erosion is responsible for the gradual wearing away of the evidence of impact craters. Wind is able to carry small particles that can slowly chafe and wear away the jagged and steep slopes, while water likewise can carry soil away. Both of these processes smooth the edges of an impact crater. Given enough time, the crater's edges could be sanded down by erosion to the point that a crater looks no different from any other valley.

What do dinosaurs don't have?
Dinosaurs aren't as intelligent as we are but they had small brains. if you want to know more about them ask me I can answer them.---ANSWER---To answer this question with any sensible answer is virtually impossible. We simply have not got enough evidence to say.I can tell you that probably dinosaurs did not have 6 legs and PlayStation's but for me this is not sensible.A lot of the common misconceptions of dinosaurs are possibly not true.Dinosaurs were cold blooded - Increasing evidence suggest that dinosaurs were in some instances warm blooded. A famous example is a Thescelosaurus fossil found in South Dakota in 1993 nicknamed "Willo". The significance of this fossil was the scientists found a fossilized heart. It proved that at least this species had a high metabolism which is indicative of warm blooded animals.Dinosaurs had scaly skin - Undeniable evidence says that many species of Therapod dinosaurs had feathers. In fact it is generally excepted now that birds evolved from dinosaurs.Dinosaurs all laid eggs - This is probably true. There is no real evidence of dinosaurs having live young. In 1947 in New Mexico, Edwin Hobart found some Coelurosaurus fossils that seemed to have the fossil of a juvenile inside it. Instead of accepting it was an example of live birth, it was concluded that the juvenile was probably the dinosaurs last meal.Some close relatives to dinosaurs did have live young. Some species of Ichthyosaurs definitely had live young.
