One piece of evidence that supports the Theory of Plate Tectonics is found in the observation of rocks on either side of the Mid-Atlantic Ridge, shown in the picture provided. Plate Tectonic theory is supported because, as you move out from the Mid-Atlantic Ridge, the rocks –

become thicker and thicker.

Scientists theorized that the continents were once joined together even before they had modern evidence from rocks and fossils. Using only maps, they observed that –
continents with the most temperate climates were found near the Equator.

Amount of water on the planet
Proximity to the Sun

Earth is currently 150 million km away from the Sun. If Earth was 200 million km away from the Sun, it would no longer support life because -
the surface water would evaporate.

the oxygen would leave the atmosphere.
there would be less exposure to solar wind.
