The dwarf planet Pluto is located where?

63% Answer Correctly

	in the Kuiper Belt
	between the orbits of Jupiter and Saturn
	outside the solar system
	in the asteroid belt

Solution

The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.

The energy posessed by a thrown baseball is an example of what kind of energy?

79% Answer Correctly

	kinetic
	gravitational
	potential
	transitional

Solution

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.

Which of the following is not true of light waves?

62% Answer Correctly

	travel faster than sound waves
	are mechanical waves
	can travel through a vacuum
	are electromagnetic waves

Solution

Unlike mechanical sound waves that require a physical medium for propagation, light waves are electromagnetic and can travel through empty space. Light waves are also much faster, travelling at 186,000 m/s vs. 343 m/s for sound waves.

Meteoroids, meteors and meteorites are categorized based on which of the following?

45% Answer Correctly

	their temperature
	their location
	their density
	their size

Solution

Smaller rocks shed by asteroids and comets are called meteoroids. When these rocks reach Earth's atmosphere, they burn up in the mesosphere and become meteors. If a meteor manages to reach the Earth, it is called a meteorite.

Which is the proper order of Earth's atmospheric layers from the surface up to space?

57% Answer Correctly

	mesosphere, thermosphere, stratosphere, troposphere
	stratosphere, troposphere, mesosphere, thermosphere
	troposphere, stratosphere, mesosphere, thermosphere
	thermosphere, mesosphere, stratosphere, troposphere

Solution

The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
