How dinosaurs extinct from earth and what happen

Since the dawn of time, dinosaurs have captivated the imaginations of people all over the world. But what happened to them? How did these incredible creatures go extinct? In this blog article, we will explore some of the theories as to why dinosaurs went extinct and how it could have happened. We’ll look at how climate change and asteroid impacts may have contributed to their demise, as well as more recent scientific theories on what actually caused their extinction. Finally, we’ll examine how current events are still being shaped by prehistoric events like this.

How dinosaurs extinct

Dinosaurs went extinct around 65.5 million years ago, at the end of the Cretaceous period. There are many theories about why dinosaurs went extinct, but the most popular theory is that a comet, asteroid, or meteor hit the earth, causing all dinosaurs to die. This event is known as the K-T event.

Introduction

For centuries, dinosaur extinction has been a mystery that has fascinated and perplexed scientists. How did these magnificent creatures simply disappear from the planet? What could have reason such an event to occur?In this blog post, we will take a detailed look into the various theories of how dinosaurs went extinct from Earth and what might have happened during this pivotal period in history. We will also discuss what it means for us today and how our lives may be affected by their disappearance. Get ready to explore one of nature’s greatest mysteries!

The asteroid impact theory

The asteroid impact theory is the most widely accepted explanation for the extinction of dinosaurs. It suggests that a large asteroid struck the earth, causing widespread devastation and killing off the dinosaurs.

There is evidence to support this theory, including the fact that there is an impact crater in Mexico that matches up with the time of the dinosaurs' extinction. Moreover, there is a layer of iridium-enriched clay all around the world that could have come from an asteroid.

However, some scientists question whether an asteroid could have caused such widespread destruction. They point to other factors, such as disease or climate change, that may have played a role in the dinosaurs' demise.Regardless of the cause, there is no doubt that the dinosaurs are gone and they are not coming back!

Volcanic activity

Volcanic activity is one of the leading theories for why dinosaurs went extinct. It's thought that a massive volcanic eruption spewed so much ash and dust into the atmosphere that it blocked out the sun, causing global cooling and an eventual ice age. This would have made it difficult for dinosaurs to survive, as they would have been unable to find food.

Climate change

Over the years, there has been much debate over what caused the dinosaurs to go extinct. The most popular theory is that a comet, asteroid, or meteor hit the earth, causing all dinosaurs to die. However, new research suggests that climate change may have played a role in their extinction as well.

A study published in the journal Science found that there was a sharp decrease in global temperatures around the time that the dinosaurs went extinct. This sudden cooling could have made it difficult for them to survive. Additionally, it’s thought that the changes in temperature may have also impacted their food supply, making it harder for them to find enough to eat.

While more research is needed to determine exactly what happened, it’s clear that climate change played a role in the extinction of the dinosaurs. As we face our own climate crisis today, it’s important to remember that even small changes in temperature can have major effects on our planet and its inhabitants.

Disease

The dinosaurs went extinct around 65.5 million years ago, give or take a few thousand years. There are a number of theories about what might have caused their demise, but the most likely culprit is a massive asteroid strike.

This event, known as the K-T boundary, was devastating for the dinosaurs. The asteroid hit with the force of a hundred trillion atomic bombs, and created a massive crater measuring 150 kilometers across. It also unleashed an incredible amount of dust and debris into the atmosphere, which blocked out the sun and caused global cooling.

The dinosaurs couldn’t survive in this new environment, and over the course of a few thousand years they died out completely. This was a major blow to the ecosystem, as the dinosaurs had been dominant for 150 million years. But it opened up new opportunities for other animals, and eventually led to the rise of mammals.

Competition from mammals

Today, dinosaurs are widely thought to have been extinguished by a comet or asteroid impact 65 million years ago. But new research suggests that the competition from mammals may have played a role in their demise.

A study published in the journal Science suggests that the rise of mammals may have contributed to the extinction of dinosaurs. After the dinosaurs went extinct, mammals flourished and took over many of the ecological niches that had been occupied by dinosaurs.

The study's author, Dr. Nicholas R. Longrich, argues that it was not just the comet or asteroid impact that caused dinosaurs to go extinct, but also the competition from mammals. He points to several examples of how mammals were able to outcompete dinosaurs.

For instance, he notes that many small mammal species are nocturnal, while dinosaurs were diurnal. This meant that they were able to avoid competition with dinosaurs for food and other resources during the day. In addition, mammals are able to reproduce more quickly than reptiles like dinosaurs, which allowed them to take advantage of opportunities when they arose.

Dr. Longrich believes that it was this combination of factors – the comet or asteroid impact and competition from mammals – that led to the extinction of dinosaurs. While more research is needed to confirm his hypothesis, it provides an interesting new perspective on why these creatures went extinct.

Conclusion

Dinosaurs have been extinct from Earth for millions of years and the exact cause is still unknown. Several theories exist as to why this extinction event happened, but none of them can be conclusively proven. What we do know is that whatever caused it was catastrophic enough to wipe out an entire species of animals, leaving us with only fossils and other evidence to piece together their story. Whatever the reason may be, it serves as a reminder that life on Earth is fragile and can change in unexpected ways at any moment.

Increasing Earth's Gravity and Bio-Evolution

Hi RAFIA ROMAN, Did the impact of the meteorite or the increase in the earth's gravity destroy the dinosaurs? Ramin: Assume that the big meteorite collide the earth 65 million years ago and declined the big dinosaurs. Why the remained small reptiles couldn’t get bigger again. The earliest reptiles which were amphibious were very small but they could get bigger and made the dinosaurs. Then it becomes clear that the factor which caused them to extinction is still remained and doesn’t allow today reptiles to get bigger. So the collision of the big meteorite with earth and the formation of dust can not be supposed as the factor of dinosaurs decline because that collision occurred at that time and the effect of dust and smoke have been disappeared and there was no later effect on animals. The theory of the increasing of the gravity says by increasing of the gravity the ability of blood system of these animals decreased gradually. So animals which had weaker blood system become smaller or extinct. Scientists think that the decline factor which was the big meteorite collided at the time and everything is finished and they can form new giant animals.
