Consider the indicated events in the history of the universe that have helped make human life possible. Rank the events based on when they occurred, from longest ago to most recent. To rank items as equivalent, overlap them. Note: If two events occurred within seconds of each other, rank them as equivalent.

1. the Big Bang & the universe begins to expand
2. elements such as carbon and oxygen first exist
3. nuclear fusion begins in the Sun
4. earliest life on Earth
5. dinosaurs go extinct
6. earliest humans

These events are already in right order.

1. the Big Bang & the universe begins to expand

2. elements such as carbon and oxygen first exist

3. nuclear fusion begins in the Sun

4. earliest life on Earth

5. dinosaurs go extinct

6. earliest humans

Explanation:

1. The Big Bang & the universe begins to expand

Big Bang happened about 13.8 billion years ago and then the universe started expanding from the size of electron to it's today's size.

2. elements such as carbon and oxygen first exist

Oxygen and Carbon lies in the category known as elements of life. They are not the production of big bang rather they have been produced in the stars much later. In the fusion reactions lighter elements combined to form heavier elements and as the heavier elements are unstable, they resulted in the explosion of stars and in that explosion these life elements carbon and oxygen were produced.

3. nuclear fusion begins in the Sun

Nuclear fusion on started when its temperature reaches 10 million degrees. In these reactions hydrogen is consuming to form heavier nuclei.

4. earliest life on Earth

Earliest life on earth was started 3.8 billion years ago.

5. dinosaurs go extinct

65 million years ago, dinosaurs went extinct in an event of Cretaceous-Tertiary.

7. Earliest Humans

66 million years ago, soon after the extinction of dinosaurs, earliest human life was started.

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day
