During continental drift, the drifting plates move across which of the following?

50% Answer Correctly

	fault lines
	water
	sediment
	liquid mantle

Solution

The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.

	primarily solid
	liquid

Solution

The Earth's core is divided into the liquid outer core (1,430 miles or 2,300 km radius) and the solid inner core (745 miles or 1,200 km radius).

In cell biology, what part of the cell contains organelles?

54% Answer Correctly

	nucleus
	cell wall
	cytoplasm
	cell membrane

83% Answer Correctly

	platelets
	plasma
	white blood cells
