- C.
Sound waves have shorter wavelengths than light waves
- D.
Sound waves are a source of energy but light waves are not.
Correct Answer
B. Sound waves travel at a slower speed than light wavesExplanation
Sound waves and light waves are both forms of waves, but they have different properties. One way in which they are different is their speed. Sound waves travel at a slower speed compared to light waves. This is because sound waves require a medium, such as air or water, to travel through, while light waves can travel through a vacuum. The speed of sound waves also depends on the properties of the medium, whereas the speed of light waves is constant in a vacuum. Therefore, sound waves and light waves have different speeds, with sound waves being slower.Rate this question:

- D.
Because of changing angles of the earth-moon-sun system as the moon orbits the earth the moon orbits the earth
Correct Answer
D. Because of changing angles of the earth-moon-sun system as the moon orbits the earth the moon orbits the earthExplanation
The moon phases occur because of the changing angles of the earth-moon-sun system as the moon orbits the earth. As the moon moves around the earth, the angle between the sun, earth, and moon changes, causing different amounts of sunlight to be reflected by the moon. This results in the different phases of the moon that we observe from earth. The gravitational pull of the earth-moon-sun system also plays a role in the moon's orbit, but it is not the main reason for the moon phases.Rate this question:

6.E.2.2 Where are earthquakes and volcanoes most often located?
- A.
Center of crustal planes
- B.
Edges of crustal plates
- C.
Center of continents
- D.
Edges of continents
Correct Answer
B. Edges of crustal platesExplanation
Earthquakes and volcanoes are most often located at the edges of crustal plates. This is because the Earth's crust is made up of several large plates that are constantly moving and interacting with each other. At the edges of these plates, there is a lot of tectonic activity, such as subduction zones where one plate is forced beneath another, or transform boundaries where plates slide past each other. These interactions can cause the crust to become unstable, leading to earthquakes and volcanic eruptions. In contrast, the center of crustal planes and continents are generally more stable and less prone to tectonic activity.Rate this question:

By sedimentary deposits after rock is weathered, eroded and transported transported
- D.
D. by the suspension of sediment in water column of a body of water
Correct Answer
B. By the disintegration and weathering of rocks such as limestone, granite, quartz and shaleExplanation
Sandy soil is formed by the disintegration and weathering of rocks such as limestone, granite, quartz, and shale. This process involves the breaking down of these rocks into smaller particles over time, which eventually form sandy soil. The accumulation of dead and decayed organic matter can contribute to the fertility of the soil, but it is not the primary factor in the formation of sandy soil. Similarly, sedimentary deposits after rock weathering, erosion, and transportation can contribute to soil formation, but they do not specifically result in sandy soil.Rate this question:

- D.
They attract birds and insects that spread pollen
Correct Answer
D. They attract birds and insects that spread pollenExplanation
The benefit of flowers on some plants is that they attract birds and insects that spread pollen. This is important for the process of pollination, where pollen is transferred from the male reproductive organs of a flower to the female reproductive organs. This allows for fertilization and the production of seeds, which is necessary for the plant's reproduction and survival. Flowers often have bright colors and produce nectar to attract birds and insects, who inadvertently pick up pollen on their bodies and transfer it to other flowers as they feed or move around.Rate this question:
