Acap Science Review

Which of these is MOST LIKELY to cause natural pollution?

• a drought

• an avalanche

• heavy snow

• volcanic activity

Jay and Jeff were recording the class weather data each day in March. This particular morning, they used the sling psychrometer seen here. What kind of weather data did they record with the sling psychromter?

• wind speed

• air temperature

• air pressure

• relative humidity

Tiny plastic pellets, like the pellets in the image, enter marine ecosystems through accidental spillage or by the decomposition of plastic wastes.

How do these pellets affect marine ecosystems?

• A)Though harmless, these pellets spoil the natural beauty of the ecosystem.

• B)They sink to the bottom of the seafloor and form the foundations of extensive coral reefs.

• C)They are consumed by fish and marine mammals and block the digestive systems of these organisms.

• D)They degrade quickly on coming in contact with the salt water, affecting the quality of the water

Without the Sun, the planets would travel in a straight line. This fact represents Newton's law of _____________: an object stays in motion unless an outside force acts on it.

• inertia

• acceleration

• action-reaction

• gravitational attraction

Which statement BEST hypothesizes the evolutionary history of the area shown?

• A)The area was once an ocean and was replaced by taiga and coniferous forest.

• B)The area was once covered by an ocean and was replaced by temperate deciduous forest.

• C)The area was once a temperate deciduous forest and was replaced by a freshwater lake.

• D)The area was once a freshwater lake, but it was replaced by the expansion of an ocean.

Day and night are the result of the earth's rotation on its own axis and its location from the sun. As the earth spins on its axis, parts of the planet are in the sun while others are in the dark. In other words, the sun appears to rise and set. The parts of the world that are in daylight get warmer while the parts that are dark gradually lose the heat they absorbed during the day.

What fractions of the earth are in day and night at any time?

• Depends on the season

• 1/4 in day and 3/4 in night

• Depends on the tilt of the Earth

• 1/2 in the day and 1/2 in the night

Any collection of things that have some influence on one another can be thought of as a system. When we talk about a system, we are also talking about all the parts that should be included, how those parts interact with one another, and to how the system as a whole relates to other systems. We think of Earth as both an open and a closed system: energy enters and leaves (open system) but matter does not (closed system). Matter flows between reservoirs or sinks along pathways or fluxes.

There are three types of reservoirs in the lithospheric cycle: igneous, metamorphic and sedimentary rocks. Various processes, such as burial and melting, volcanism, or erosion move this material from one reservoir to another. The major process that drives the rock cycle is plate tectonics, the movement of Earth's crustal plates that is driven by convection currents of the magma within the Earth itself.

Students are investigating the types of rocks found in various locations throughout California, the state where they live and attend school. What hypothesis might the students formulate to guide their research on rock formation, given that they live in California?

• If volcanoes are the source of land masses in California, then most of the rock in the state should be igneous.

• If California is the site of several plate boundaries, we would expect to see mostly metamorphic rock at the boundary sites.

• If there is movement at plate boundaries and sediment is the result of erosion, then we would expect to find mostly sedimentary rock at plate boundaries.

• Because there are mountainous regions in California and sedimentary rock is the result of erosion, we would expect to find mostly sedimentary rock in California,
