An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?

59% Answer Correctly

Jupiter and Saturn

Mercury and Venus

Mars and Jupiter

Mars and Earth

2

Which of the following is the correct order for types of radiation from longest to shortest wavelength?

60% Answer Correctly

microwaves → radio waves → visible light

infrared waves → microwaves → ultraviolet light

visible light → ultraviolet light → radio waves

radio waves → visible light → gamma rays
Solution

The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation.  From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.

3

Examples of primary consumers include:

54% Answer Correctly

cows

rats

fish

all of these
Solution

Primary consumers (herbivores) subsist on producers like plants and fungus.  Examples are grasshoppers, cows, and plankton.

4

The coldest point in the Earth's atmosphere is reached in which atmospheric layer?

52% Answer Correctly

troposphere

stratosphere

thermosphere

mesosphere
Solution

In the mesosphere, temperature again drops as altitude increases until the coldest point in the Earth's atmosphere, the mesopause, is reached where temperatures fall to −225 °F (−143 °C).

5

Which of the following substances gives up positively charged hydrogen ions (H+) when dissolved in water?

55% Answer Correctly

base

solution

acid

alkaline
Solution

An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.
