Comp Sci 2 - PMA 3 Review

1. 7.E.6.2 - Florida and the Atlantic ocean surrounding Florida are a part of the North American plate. Therefore, although Florida faces the Atlantic ocean, it is not at a tectonic plate boundary with an oceanic plate. However, plate boundaries can occur between continental plates and oceanic plates as shown in the figure below.

What can you conclude from this figure?

• The two tectonic plates are sliding past each other horizontally along Earth’s surface.

• The two tectonic plates are moving apart to create a mid-ocean ridge on the sea floor

• The two tectonic plates are converging so that a mountain range forms on the continent.

• The two tectonic plates are diverging causing the continental plate to buckle and form mountains

7.P.10.1 - Use the diagram of the Electromagnetic Spectrum. Which statement below is correct when comparing Visible Light (or white light) waves to X-rays waves?

• X-ray waves have a longer wavelength, higher frequency and less energy than Visible light waves.

• Visible light waves have a longer wavelength, higher frequency and less energy than X-ray waves.

• Visible light waves have a shorter wavelength, lower frequency and greater energy than X-ray waves.

• X-ray waves have a shorter wavelength, higher frequency and greater energy than Visible light waves.

7.E.6.4 - Over time, repeated cycles of heating and cooling can cause a rock to crack. The rock may then break into smaller pieces. What is this process called?

• deposition

• erosion

• subsidence

• weathering

7.E.6.2 - When two tectonic plates meet, they can interact in different ways. Their movements can cause changes to Earth’s surface. The diagram below shows a boundary between two tectonic plates. Which statement best describes the interaction between the plates?

• An undersea volcanic mountain is being built up over a hot spot.

• Sea floor is being built up as two plates diverge and volcanoes form at the boundary.

• Sea floor is being destroyed as two plates converge and volcanoes form at the boundary.

• A fault is being created as two plates slide past each other and volcanoes form at the boundary.

7.L.16.1 – Heredity is explained by which of the following?

• an organism’s genetic make-up of allele frequency

• the scientific study of genetics

• the genetic material that carries information about an organism

• the passing of traits from parent to offspring through DNA

7.E.6.4 - The picture below shows the rock layer in one part of the Grand Canyon. Based on the law of superposition, what is the order of these rock layers, from oldest to youngest?

• 1, 2, 3, 4

• 2, 1, 4, 3

• 3, 4,1, 2

• 4, 3, 2, 1

7.E.6.5 - Subduction occurs when one plate slides beneath another plate. The figure below shows the process of subduction. Notice that the oceanic plate slides beneath the continental plate. What happens when the crustal plates move as shown in the figure?

• An ocean forms

• Volcanic mountain ranges form

• Sea-floor spreading occurs as the oceanic plate moves

• A transform boundary forms where the subduction occurs

7.L.17.2 - Which of the following is an example of commensalism?

• A bird is hunted by a cat, killed, and eaten

• A bird eats berries and then spreads the seeds.

• A bird finds an existing hole in a tree and builds a nest in it.

• A bird finds a small shellfish on a beach, cracks its shell, and eats it.

7.E.6.5 - The figure below shows part of what scientists think is happening in Earth’s mantle. What process does the figure show occurring in the mantle?

• Hot rock expands, becomes less dense, and rises toward the surface of Earth.

• Hot rock expands, becomes denser, and rises toward the surface of Earth.

• Hot rock becomes less dense and moves towards the outer core

• Hot rock becomes denser and moves towards the lithosphere

7.L.16.1/7.L.16.2 - Look at the diagram. Which of these choices should be placed in the box with the question mark?

• AA

• Aa

• aa

• AA or aa, but not possible to determine which one
