PROBLEM: A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge. <sep>Where does the sediment in a flooding river come from, and where does it eventually come to rest?<sep>It comes from eroded rock and land and rests when the water receeds

SOLUTION: Yes

PROBLEM: For thousands of years, people have found fossils. The fossils caused curiosity about Earths past. How did these organisms live? What type of world did they live in? Fossils can tell us a lot about Earths history. In ancient times, fossils inspired myths and stories. These stories included tales of monsters and other incredible creatures. What type of creature do you know that could inspire such stories? Of course, dinosaur fossils were once mistaken for dragons bones. Two thousand years ago, people discovered fossils in China. At the time, they were thought to be dragon bones. We know now that these were not bones, but fossils. So what is the difference? <sep>How long ago and in what country were the first documented fossils found?<sep>2000 years ago in China

SOLUTION: Yes

PROBLEM: Miss Anderson dined out, and preferred to suppose that she had no time to think until she was on her way home along the empty road round Jakko at eleven o'clock that night. Then it pleased her to get out of her rickshaw and walk. There was an opulent moon, the vast hills curving down to the plains were all grey and silvery, and the deodars overhead fretted the road with dramatic shadows. About her hung the great stillness in a mighty loneliness in which little Simla is set, and it freed her from what had happened, so that she could look at it and cry out. She actually did speak, pausing in the little pavilion on the road where the nursemaids gather in the daytime, but very low, so that her words fell round her even in that silence, and hardly a deodar was aware. 'I will not go now,' she said. 'I will stay and realize that he is another woman's husband. That should cure me if anything will--to see him surrounded by the commonplaces of married life, that kind of married life. I will stay till she comes and a fortnight after. Besides, I want to see her--I want to see how far she comes short.' She was silent for a moment, and the moonlight played upon her smile of quiet triumph. 'He cares too,' she said; 'he cares too, but he doesn't know it, and I promise you one thing, Madeline Anderson, you won't help him to find out. And in five weeks I will go away and leave my love where I found it--on a mountaintop in the middle of Asia!' <sep>Why does Miss Anderson not want to go now?<sep>She loves the moon

SOLUTION:
No
