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:
13.72units
Explanation:
Given parameters:
Coordinates of the two points = (-5.2, 7) and (3,- 4)
Unknown:
Distance between the two points = ?
Solution:
To find the distance between two points, we use the mathematical expression below;
D = 
From the given coordinates;
x₁ = -5.2 x₂ = 3
y₁ = 7 y₂ = -4
Now; input the parameters and solve;
D = ![\sqrt{[3-(-5.2)]^{2} + (-4 -7)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5B3-%28-5.2%29%5D%5E%7B2%7D%20%2B%20%28-4%20-7%29%5E%7B2%7D%20%20%7D)
= 
= 13.72units
The distance between the two points is 13.72units
Answer:
c. Chemical weathering
Explanation:
One of the famous landmarks in New York City is "The Statue of Liberty." It was built in<em> 1886</em> as a gift to the Americans from France.
The statue is covered with<em> copper sheets</em>, thus, it used to have a brown color. However, over time, the color turned into greenish-blue. This is because<u> the copper sheets underwent chemical weathering</u>. Such process occurred as a result of the reaction of copper with Oxygen in the air and with water. It produced<em> "copper carbonate,"</em> which is<em> greenish-blue</em> in color. Such color was noticeable in<em> </em>1900<em>, </em>but it covered the entire statue in <em>1906.</em>
