Venus will help us understand what happens when the greenhouse effect is really extreme but it's not a really good example of what will happen to Earth because of human activities. Life on Earth would completely die due to the extreme temperatures way before reaching even half of the concentrations of carbon dioxide on Venus. Mars doesn’t really have any greenhouse effects. Mars does have some atmospheric carbon dioxide but almost no atmosphere but the atmosphere it does have is so thin that it cannot keep energy from the Sun. That’s why there are extreme temperature contrasts between day and night and sun or shade. However, most scientists say that Mars used to be warmer in and even had oceans, which means that the atmosphere was also very different. About 3600 million years ago, something happened and the planet evolved towards its current state. studying the planet could tell us what could have caused such a huge change
Answer:
Definition: U-shaped valleys form through glacial erosion. Glaciation develops in established v-shaped river valleys where the ice erodes the surrounding rocks to create a “U” shaped valley with a flat bottom and steep sides. Glacier movement is driven by gravity
Rio Grande River sources: Rio Grande Natural Forest, San Juan Mountains, Canby Mountain
And scientists say it will take natural processes 6,000 years to refill the reservoir
B. North Sea, it is well known for its fierceness. Throughout the year there are strong storms that hit the coasts of the countries that surround it.This huge raft of seawater of about 750,000 square kilometers, an "arm of the Atlantic" we could say, receives marine currents from the other side of the world and is stirred up affecting the British Isles, Norway, Denmark, Germany, Holland, Belgium and France with big tides and scary storms.
