As explained by the model, which of the following changes would cause an increase in Earth's average temperatures? Select all of the answers that apply.
A. an increase in the solar radiation that strikes the atmosphere
B. an increase in the amount of light that is reflected by Earth's surface
C. an increase in the amount of light that the atmosphere reflects into space
D. an increase in the concentration of greenhouse gases in the atmosphere
E. an increase in the concentration of oxygen, which is not a greenhouse gas, in the atmosphere
A, B and D i think?
so sorry if its wrong tho
A. an increase in the solar radiation that strikes the atmosphere
D. an increase in the concentration of greenhouse gases in the atmosphere
Well, let me tell you, if we turn up the sun's heat and give it a little more oomph, that's definitely going to make things hotter. And if we start filling up the atmosphere with more greenhouse gases, it's like wrapping the Earth in a warm and cozy blanket. So, those two are the answers that would lead to an increase in average temperatures. However, sorry to disappoint you, but increasing the amount of light reflected by Earth's surface or the amount of light the atmosphere reflects into space won't really have a warming effect. And as for increasing the concentration of oxygen, well, it's great for us to breathe, but it doesn't contribute to the greenhouse effect and won't really affect temperatures. So, let's say A and D are the hot picks here.
According to the information provided, the changes that would cause an increase in Earth's average temperatures are:
A. An increase in the solar radiation that strikes the atmosphere.
D. An increase in the concentration of greenhouse gases in the atmosphere.
So, options A and D would result in an increase in Earth's average temperatures.
To determine which of the changes listed would cause an increase in Earth's average temperatures, we can analyze each option:
A. An increase in the solar radiation that strikes the atmosphere: This change would cause an increase in Earth's average temperatures. When more solar radiation reaches the Earth's atmosphere, it leads to more heat absorbed by the planet, causing a rise in temperatures.
B. An increase in the amount of light that is reflected by Earth's surface: This change would actually cause a decrease in Earth's average temperatures. When more light is reflected by Earth's surface, less heat is absorbed, leading to cooler temperatures.
C. An increase in the amount of light that the atmosphere reflects into space: This change would cause a decrease in Earth's average temperatures. Similar to option B, when more light is reflected back into space by the atmosphere, less heat is retained by the planet, resulting in cooler temperatures.
D. An increase in the concentration of greenhouse gases in the atmosphere: This change would cause an increase in Earth's average temperatures. Greenhouse gases, such as carbon dioxide and methane, trap heat in the atmosphere and act as a blanket around the planet. When their concentration increases, more heat is retained, leading to higher temperatures.
E. An increase in the concentration of oxygen, which is not a greenhouse gas, in the atmosphere: Oxygen is not a greenhouse gas and does not directly contribute to the greenhouse effect. Therefore, an increase in oxygen concentration would not have a significant impact on Earth's average temperatures.
Based on the analysis, options A and D would cause an increase in Earth's average temperatures. Therefore, the correct answers are A and D.
