Questions:
1.Why are the four major layers of the atmosphere separated where they are?
2.What increases the temperature in the stratosphere?
3.Can planes fly in the mesosphere?why or why not?
4.On what does the temperature in the thermosphere depend?


Answers:
1.They are separated because of their different temperatures.
2.The high concentration of ozone in the stratosphere.
3.No.Because there is not enough oxygen to breathe.
4.It depends on the ultra violet radiation that the oxygen absorbs.

The Nitrogen Cycle

Discussion Questions:
1.The atmosphere is 80% nitrogen:why do you think plants and animals can't use nitrogen as it is found in the atmosphere?
2.Explain what is meant by nitrogen fixation?
3.What is the role of bacteria in the nitrogen cycle?
4.why don't legumes need nitrogen-containing fertilizer?
5.Why is nitrogen so important for living things?
6.What are the processes involved in the nitrogen cycle?

Answers:
1.Because most nitrogen is found as a gas.
2.Nitrogen fixation occurs when bacteria convert nitrogen gas into organic compounds that living organisms can take up.
3.The bacteria are the ones responsible for converting nitrogen gas into ammonium ions and convert ammonia from dead animal excretions.
4.Because legumes have bacteria living in their roots which can fix nitrogen.
5.Because it is an essential element for life and it is important for photosynthesis to occur.
6.Nitrogen fixation, ammonification, nitrification, denitrification, assimilation.

Computer Science is practiced by mathematicians, scientists and engineers. Mathematics, the origins of Computer Science, provides reason and logic.
                                 Computer science is a discipline that spans theory and practice. It requires thinking both in abstract terms and in concrete terms. The practical side of computing can be seen everywhere. Nowadays, practically everyone is a computer user, and many people are even computer programmers. Getting computers to do what you want them to do requires intensive hands-on experience. But computer science can be seen on a higher level, as a science of problem solving.
