plants with seeds evolved from simpler plants which evolved from single celled organisms

3.5 billion years ago that's when the earth was cooled down
Earth cooled down enough for rain to fall.
When molecules are cooled down, they lose energy and move more slowly, causing them to come closer together and form a solid or liquid state, depending on the temperature.
The convection currents will stop
Some of the earth's atmosphere was made from volcanic eruptions in the past and also when a comet struck earth like when the dinosaurs were alive it cooled down the planet.
As the Earth cooled down, gases such as carbon dioxide and water vapor in the atmosphere started to condense and form oceans. This led to a reduction in the amount of these greenhouse gases in the atmosphere, resulting in a shift towards the composition seen today with nitrogen dominating the atmosphere.
At the feezing point the liquid become a solid.Freezing is a physical change.
when water vapour is cooled it condenses and falls as rain
They slow down and come closer together forming a liquid. Then further cooling will produce a solid.
If the mantle of the earth interior were to cool down the convection currents and plate tectonics would stop. That would mean that there would be no more earthquakes or volcanoes.
The Earth cooled down after its formation due to the loss of heat from its interior through a process called radiative cooling. As the Earth's surface solidified, heat continued to be transferred to the surface and eventually dissipated into space, causing the Earth's overall temperature to decrease gradually over time.
