The diagram shows that ∠2 and ∠4 are the vertical angles.
<h3>What are vertical angles?</h3>
Vertical angles are the angles that are opposite of each other when two lines cross.
The statements are:
1. < 2 & < 4 are vert. angles
2. Lines M & N intersect at P
3. < 2 & < 3 are a linear pair
4. m < 2 + m < 3 = 180
5. <3 and < 4 are a linear pair
6. m < 3 + m <4 =180
7. m < 2 + m < 3 = m < 3 + m < 4
8. m < 2 = m < 4
9. < 2 =~ <4
Here are the reasons:
1. Given
2. Def of vertical angles.
3. Def if. Linear pair
4. Angle addition postulate
5. Def of a linear pair
6. Angle addition postulate
7. Substitution property
8. Subtraction property
9. Def of =~ angles.

One way is that the sun is heating up the world causing droughts and causing the water level to rise to cause floods
Answer: D. both A and B
Explanation:
Earth is the only planet that is capable of supporting life as we know it due to the presence of temperature, oxygen, an atmosphere and energy.
All the above contribute in the following ways;
- Atmosphere - The atmosphere is sort of like a protective barrier around earth. It destroys a lot of foreign objects that fall on earth and traps the sun's rays such that we keep us adequately warm. It also contains both oxygen and carbon dioxide which living things rely on.
- Energy - The presence of energy sources on Earth enables us to be able to survive. Energy sources like fire, water, and solar enable us to do things such as cooking and electricity generation, that ensure our survival.
- Nutrients - The nutrients available on Earth ensure that living things can grow and survive.
- Temperature - A very important factor, Earth has the right amount of temperature necessary for the proliferation of life. It is not too cold that living things are unable to metabolize food and freeze and is not too hot that life cannot survive.
A permeable rock breaks down quicker than a rock that is not so permeable because there is less space for anything (i.e. water) to get in the not so permeable rock in order to widen the holes and ultimately break the rock. On the other hand, a permeable rock is full of holes and will break down because of the many holes available to widen.
