This measures the probability of an interaction occuring. For typical interactions between ions and electrons, or between two nuclei, these cross sections are generally measured in barns. (Science: anatomy) a transverse cut through a structure or tissue. The opposite of a cross-section is a longitudinal section.
Gravitational force, keeps the molecules in the atmosphere from moving into space. Gravity's influence is stronger near the earth's surface and weaker
There is something new! There is now 5 seasons instead of 4. Everyone is really happy. It is called the second summer. This is pretty cool because summer does not last very long, and with a second summer it could last longer.
Some people might not enjoy having a longer summer though. It is a big change for everyone. Me and my friends like summer because there is more time for us to do things together, and spend more time together. Summer is fun for a lot of people for example, there is no school. When you dont have school it makes more time for people to spend with family and friends.
If there is a second summer there is more time to spend outside, with friends, going on trips with family, and lots of other things. This is because there would be more time off school. If there was more time off school then there is more free time to do what ever you want. But.... some people do not like summer as much as others. The people that dont really like summer would just have to get used to it. There is nothing you can do that is part of earths rotation.
So if there is 5 seasons now, no one can change it. They can not change it because no one can rotate or tilt the earth. The earth tilts when it is changing seasons. No one can just go up and tilt the earth so they could have the season they want. But that is what i think would be cool if there were 2 summers. Also during summer is when family, and Friends can plan vacations. So people could go on vacation more to!
this is the best I can do❤❤
