how would the global climate be diffrent if more of earth was covered with land than water
Answers
Answer:The Earth’s surface is composed of roughly 71% water and 29% land, where the oceans hold almost 97% of all the water resources on the planet. The Earth would have been drastically different if this ratio had been reversed, with a solid landmass making up most of Earth’s surface.
Also, for this hypothetical discussion, let’s assume that everything would be opposite, which means that the high landmasses would be turned into deep trenches. The differences would be innumerable, with the Earth supporting a totally different form of life, if life was even possible! With this strange premise firmly in our minds, let’s see what living on such a planet would entail.
The Temperature of the Earth Would Increase
The oceans play a pivotal role in decreasing Earth’s temperature. Huge amounts of water evaporate from oceans, thereby preventing a drastic rise in Earth’s temperature during each day. If most of the surface was land, however, then the land would be extremely hot, turning most of it into deserts, while the ice caps would grow smaller, flooding all the nearby land. Oceans moderate temperature, since water has a high specific heat capacity, which means that it absorbs more heat without a significant rise in temperature, unlike the land. Without such huge water reservoirs, the temperature rise of Earth would be far from gradual.Global Warming MemeAnother thing that could happen is a decrease in greenhouse gas absorption by the oceans. This means that oceans, which are natural carbon dioxide sinks, would be unable to absorb all the extra greenhouse gases, thus leading to a highly saturated atmosphere. Global warming would speed up and Earth’s temperature would rise, similar to Venus, where global warming is abundant.

The Climate Would Be Very Erratic
Oceans help to properly distribute heat around the Earth due to their continuous cycle of evaporation and condensation. Water evaporates from oceans and other water bodies into the air and also transpires from land plants and animals into the air. If the oceans were converted into land, then the water cycle would be disturbed and the amount of precipitation on land areas would reduce significantly. This would lead to droughts and a high variance of land climate.
Explanation: so please mark as brainliest
Answer:
the climate with not be favourable for us to live and also,it will be hot and humid.The water cycle will not be there...so,rain will also not happen regularly...hence,there will be droghts :(
