You and your father inspect an empty house with the hopes of buying it. You walk through the rooms talking to one another, and you notice that your voices and footsteps are echoing in the big, empty house. What causes the echo?

sound waves reflecting off smooth, flat surfaces throughout the house

sound waves moving around the large rooms

sound waves moving slowly through air

sound waves refracting around corners in the empty rooms

Cletus wants to make ear protectors for people who work around loud jet engines at Hartsfield Airport in Atlanta. Which of the following materials should he experiment with for the best results?

a material that transmits sound

a material that amplifies sound

Why is a light wave not considered a mechanical wave?

A light wave travels through the vacuum of space.

A light wave is visible to humans.

A light wave moves faster than most waves.

A light wave does not have a wavelength.

How is an electromagnetic wave different from a mechanical wave?

An electromagnetic wave can travel through a vacuum, but a mechanical wave cannot.

An electromagnetic wave travels slower than a mechanical wave.

An electromagnetic wave has a larger amplitude than a mechanical wave.

An electromagnetic wave has no wavelength, but a mechanical wave has a wavelength.

Based on your observations of the prism, select the true statements.

When light travels through a prism, the light is separated by wavelength.

Humans see the different wavelengths of visible light as different colors.

The prism is being used to combine different colors of light.

The light bends when it enters the prism and again when it leaves the prism.

Why does this car appears red under a white light?

The car is reflecting only the red light while absorbing the blue and green.

The car is absorbing the red light and reflecting the blue and green.

The car is absorbing the red and green light while reflecting the blue.

The car is absorbing the red, blue and green, but our eyes can only see the red.

What is ultraviolet light

Light that has more energy than regular light so we can't see it.

Light that has less energy than regular light so we can't see it.

Light that is only given off at night.

Light that only All Might can see.

Based on your observations of the prism, select the true statements.

What are the 3 major types of rocks?

Igneous, Metamorphic, Sedimentary

Metamorphic, Igneous, Cementation

Organisms D and C clearly lived in an aquatic (water) environment. Organism A does not look like it lived in the water. What is the most likely explanation for this?

The environment changed over a long period of time. It used to be under water, but is not anymore

The fossil in layer A died on land and was carried to the water

The fossils in layer C and D did not live in the same location as the fossil in layer A

According to most scientists, what is the ultimate cause of most mass extinctions?

major change in environment or climate

evolution of new species to replace old ones

Why do scientists think that NOT ALL dinosaurs died in the Cretaceous extinction?

Birds are descendants of dinosaurs

Because birds are still living today

They have photographic evidence

A zoo in California has a living dinosaur

What is represented by the picture?

How the continents are arranged today

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

the denser ceanic crust is subducting under the less dense oceanic crust

the tectonic plates are moving away from each other.

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

the denser ceanic crust is subducting under the less dense oceanic crust

the tectonic plates are moving away from each other.

What geological forces might be responsible for this range of mountains?

erosion of the land by the ocean

deposition of sediments by the ocean

What is the source of energy that drives plate movement?

convection currents in the asthenosphere

the different densities of the oceanic and crustal plates

the friction force between the plates that move past each other

The image shows the Pacific Ring of Fire, a region of high tectonic activity. What evidence supports the theory that the tectonic activity of the region is due to the subduction of tectonic plates?

The Asia-Pacific region is dotted by many small and large islands

The region is bound by many oceanic trenches.

North America seems to be colliding with Asia at the north of the ring.

The landmasses look like they would fit together like the pieces of a jigsaw puzzle.
