how did dinosaurs die
Answers
(☞ﾟ∀ﾟ)☞Answer
Ans) We know that dinosaurs ruled the Earth for about 180 million years. Then, around 66 million years ago, a huge rock from outer space (called an asteroid) smashed into the Earth.
It crash-landed near Mexico. It shook the ground. It made big waves in the sea. Any animals and plants that were nearby would have gotten squashed or washed away!
The asteroid made lots of dust and dirt and rocks to fly up into the air. All that dust and dirt covered the planet and made the sky dark. There were many forest fires too.
Before the asteroid hit Earth, there were lots of volcanoes erupting in what we now call India. They made smoke, and ash, and gases fill up the air. We are not sure if the asteroid then hitting Earth made more volcanoes erupt. Maybe it was just very bad timing.

Answer:
The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. ... This suggests that a comet, asteroid or meteor impact event may have caused the extinction of the dinosaurs.
Explanation:
Yes, they say, Earth was indeed hit by an asteroid or comet some 66m years ago at the end of the Cretaceous period. But that was either a coincidence or the straw that broke the planet's ecological back. For the rocks also show that a series of huge volcanic eruptions was happening at the time in what is now India.
What caused global mass extinctions? Around 75% of Earth's animals, including dinosaurs, suddenly died out at the same point in time
The discovery adds to growing evidence that the dinosaurs were wiped out when a comet or asteroid crashed into Earth at the end of the cretaceous. The animal, most likely an adult triceratops, was not the last dinosaur standing, but the last survivor of their impressive reign to be identified by palaeontologists.
