QUES: Fact: I wasn't dead. After I realized this, I left my quarters. The lightscreen provided had informed me when and where official meals were taking place, but I hadn't bothered to acknowledge the invitations. It hadn't seemed relevant, somehow, given that I was still reeling over the explosion, the deaths of my crewmates, and the rescue. I've heard there are a number of stages of grief and shock; I guess I was working my way through them. Food was delivered to my quarters. Initially, I couldn't figure out whyI hadn't requested any be sent. Then I realized, someone must have noticed I hadn't left, and was nice enough to send food my way. The accompanying bottle of wine was a nice touch. I must have consumed it, too, because later on, the plates and the bottle were both empty. I spent a lot of time lying on my back on the bed, staring up at the little etched swirls in the ceiling, or slumped in the old-fashioned armchair, staring out the windows at the stars. I did a lot of staring and not moving. Man, was it good to be done with that stage. It was time to find out what hell looked like.

MY QUESTION: Why was he grief and shock, to where the food was delivered?

QUES: Have you ever looked closely at a globe? That continents look like a giant jig-saw puzzle. North America looks like it could fit next to Europe. The edge of South America matches Africa. Scientists noticed these same features. It caused them to start asking questions. They wanted to know if these continents were was connected? If so, how can something so large move so far? What could possibly have enough force to move such a giant slab of rock? Is there other evidence that can provide clues to the past positions of continents? How can answering these questions help us? A scientist named Alfred Wegener had these same questions. Wegener look at rocks on both sides of the Atlantic Ocean. He noticed they were the same type and age. He thought that the rocks must have formed side by side. He proposed that the rocks then drifted apart. One part went with North America. The other part stayed with Europe.

MY QUESTION: What features did the scientists notice

QUES: Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

MY QUESTION: Is energy required for water to move a rock?

QUES: How can you describe your location? You might use a familiar system. You might say, 'I live at 1234 Main Street, Springfield, Ohio.' You could also say, 'I live right behind the Elementary School.' This method uses the school as a point of reference. Another example is, I am at the corner of Maple Street and Main Street. Both streets may be a good reference for anyone living in your town. Scientists must be able to pinpoint a feature they are studying. Scientists use a special system to describe locations. They use latitude and longitude as a reference. Lines of latitude and longitude form a grid. You may have used a grid system while doing graphing. This grid is centered on a reference point. Zero latitude is the equator. Lines of latitude run east to west. They divide the Earth from North to South. Lines of longitude run from north to south. They divide the Earth from East to West. Zero longitude runs through Greenwich, England. You may have heard the term, Greenwich Mean Time, or GMT. The system of latitude and longitude works well for objects that do not move.
