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

50% Answer Correctly

	fault lines
	liquid mantle
	water
	sediment

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.

Poor balance could indicate an issue with which part of the nervous system?

64% Answer Correctly

	medulla
	cerebrum
	cerebellum
	spinal cord

Solution

The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.

In the foood chain, producers serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through:

47% Answer Correctly

	autotrophs
	chemosynthesis
	decomposition
	photosynthesis

Solution

Producers (autotrophs) serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis

This skeletal system is common in arthropods like insects, spiders, and crustaceans.

81% Answer Correctly

	endoskeleton
	vertebrate
	exoskeleton
	bone

Solution

An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.

Which of the following is not true about simple magnets?

63% Answer Correctly

	opposite poles attract each other
	opposite poles repel each other
	all of these are untrue
	same poles repel each other

Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.
