恐龙灭绝气候变迁说作文

英文回答：

Dinosaurs went extinct about 65 million years ago, and

the cause of their extinction is still a mystery. One of

the most popular theories is that an asteroid or comet

impact caused the extinction event. This theory is

supported by the evidence of a large impact crater in the

Gulf of Mexico. Another theory is that a massive volcanic

eruption caused the extinction event. This theory is

supported by the evidence of large volcanic eruptions in

India at the time of the extinction event. However, there

is evidence that suggests that climate change may have

played a role in the extinction event.

The Earth's climate was much warmer during the

Cretaceous period than it is today. The average global

temperature was about 10 degrees Celsius higher than it is

today. This warm climate allowed dinosaurs to thrive in all

parts of the world. However, at the end of the Cretaceous

period, the Earth's climate began to cool. This cooling

trend may have caused the extinction of many dinosaur

species. The cooler temperatures may have made it difficult

for dinosaurs to find food and survive. In addition, the

cooling climate may have caused changes in the dinosaur's

habitat. These changes may have made it difficult for

dinosaurs to reproduce and raise their young.

Climate change may have been one of the factors that

contributed to the extinction of the dinosaurs. However, it

is likely that a combination of factors, including the

asteroid or comet impact, the volcanic eruptions, and the

climate change, caused the extinction event.
