Astronomy & Space - September 2007

Just wanted to test if the average person's reasoning for basic questions is correct...

1) Who was the first person to discover the Earth is round?
2) What causes the Earth's 4 seasons?
3) True or False? When it's summer in the U.S., the Earth is farther away from the sun than if it were winter.
4) What causes the phases of the moon?
5) Before Mt. Everest was discovered, which mountain was the highest?

If a small planetoid in a disk of debris is orbiting around or spiraling in on the Sun, the debris outside of it will be going slower than the planetoid and the debris inside the planetoid will be going faster. As the debris is drawn to the planetoid by gravity, will the incoming debris result in a planet that spins clockwise or counterclockwise and why? I don't have the Physics to evaluate the effects of the Sun's gravity pulling one way on the debris and the planetoid's pulling the other. We're looking down on the system from above of course.
I know that if the whole disk has the same angular velocity that the planet will end up spinning counterclockwise like we do.

.. WHEN

1. The Earth Rotates around its own axis at a super speed of 1040 miles / hour

&

2. The Earth Rotates around the Sun at a breathtaking speed of 30 km (18.5 miles) / Second.

But we don't feel any movement ?

How is iT ?

Would we feel it if we had some planets too near to the earth?

Thinking of this makes my head rotate faster than the Earth.

Help me, Please!

Thanks in advance!
