How does plate tectonics and geological events affect the environment?

The main effects from plate tectonics are the uplift of mountains which results in snow covered mountains. These increase planetary albedo cooling the planet. This partly accounts for the current Pleistocene Ice Age, with the growth of the Alps, Rockies, Andes and Himalayas all snow covered. During the Cretaceous there was little mountain building, and the sea surface was greater due to erosion around the coasts. This led to an increased greenhouse effect from water vapour and higher temperatures globally

Conditions are more like living on  land  for creatures in the upper part of the intertidal, which is only covered with  water  at extreme high tide, so life is easier on land. conditions are more like living in the ocean for creatures in the lower part of the intertidal which is only exposed to air at extreme low tide. so basically it both worlds of land and ocean.

Yep, we’re not gonna last that long sadly
