8. Jon has a very strong fear of spiders. One day while he 5 points was lying in bed, a spider fell on his head. Jon quickly

jumped out of bed as a result of his fear. However, the

spider still managed to bite him. Jon darted toward the

door, and within seconds he collapsed to the ground. When

his mother rushed into the room to ask what was wrong,

he was unable to understand her question. He saw her

moth move, but was unable to make sense of the words.

What area of the brain did the poison affect?

If you are talking about typical sand you would find at the beach or in a river bed here on earth, there are some differences. i would say the first biggest difference is in composition and mineral make up. although the moon is largely made of the same materials as earth’s mantle and surface, the moon experiences very little weathering (no liquid water and virtually no atmosphere). “earth” sand is typically composed mostly of quartz grains. this is because quartz is highly resistant to both physical and chemical weathering. most of the other minerals originally with the quartz are broken down into fine clay and carried away, chemically eroded/ dissolved, or some combination of the two. this usually leaves only the quartz behind, and so most of the time when you see/think of sand, you are talking about quartz. without these weathering mechanisms on the moon, the “sand” (which is likely more silt or clay sized grains anyways) would consist of mostly other minerals like anorthosite, olivine, and proxene.
