PRECAMBRIAN :)a+
It is believed that the moon was created by a collision between proto-Earth and a Mars-sized planet. The moon was formed from accreted Earth collision material.
Yes it is true that scientists believe that the Earth is presently overdue for an Ice Age. The Ice Age happens in different cycles.
4.6 billion years old
Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen.
The Earth's crust is formed of plates that are in constant slow movement. Scientists believe that this movement began 3.2 billion years ago. Before plate tectonics, the Earth's surface was shaped by different processes.
first era was the Precambrian
They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
dust and ice and other partcials
A. Quaternary
scientists belive human beings first developed on earth during :- A. quaternary.
Scientist theorize that a planet-sized object collided with earth and the moon formed
Scientists believed that first the earth was a ball of fire. They believe that the earth formed around this ball of fire, thus meaning the ball of fire is the Earth's core.
Paramecium are single-celled organisms that were first discovered in the 17th century. Scientists believe paramecium have been around since the Earth was formed.
It is believed that the moon was created by a collision between proto-Earth and a Mars-sized planet. The moon was formed from accreted Earth collision material.
they think it was once part of the earth and then somehow was hit and broke away from us, but staying in our gravitational pull...
Scientists believe it does. Yes.
Scientists believe that the Moon has formed by a huge meteorite that hit Earth a very long time ago, sending parts of Earth's crust into its atmosphere. These parts started orbiting Earth for quite some time, then got together and formed into the Moon that we know of today.
