7th Science Final Review (Previously Tested Topics)

People try to conserve some resources, like fossil fuels, because they are not replaceable. Why can't these resources be replaced?

• Processes that make them take a long time.

• It is impossible to extract more from the earth.

• They must be transported long distances.

• No one can afford to buy more of them.

In all of the following examples, the quantity of the resource being used by humans is affected EXCEPT--

• fresh water used for agriculture, recreation, and tourism.

• metal ores mined and used to create building materials.

• petroleum taken from the ground and burned for fuel.

• wind power used to provide energy for homes and businesses.

Which of the following processes is driven by the energy from Earth's interior?

• Melting of rock

• Decomposition

• Photosynthesis

• Beach erosion

To be complete and accurate, a model of how material is cycled on Earth would need to include all of the following EXCEPT--

• heat from Earth's interior.

• position and motion of Earth.

• radiation from the Sun.

• movement of air, water, and rock.

Which of the following provides evidence for past tectonic plate motions?

• Glacial evidence has been found in areas where glaciers could not exist if the continents were in their current location.

• Ancient life forms preserved as fossils can tell us what organisms existed and where they were. Matching the fossils can show that land masses were once connected.

• Matching rock type and rock formations can show the way the continents were once attached.

• All of the above.

By studying the distribution of different types of fossils, geologists have determined that some plates have traveled great distances. Evidence to support this comes from the fact that--

• species of organisms in the fossil record have changed over geologic time.

• the oldest known fossil, found in the deepest rock layers, represent ocean organisms.

• fossils of organisms that lived in warm climates have been found in arctic environments.

• some fossilized organisms have only been found on one continent.

New seafloor material is formed at places in Earth's crust where--

• one tectonic plate slides beneath another and is forced downward.

• magma rises into the spaces where tectonic plates pull away from one another.

• rock is broken into pieces as tectonic plates push against one another.

• lava flow from volcanic eruptions builds up over many thousands of years.

Which of the following surface features could be caused by moving ice, but not by moving water or wind?

• Smoothing and rounding rocks of different sizes

• Movement of sediments down a mountainside

• Transporting large boulders over many kilometers

• Carving out a canyon several kilometers long

Which observations about the Rocky Mountains and the Appalachian Mountains would support the claim that exposure to weathering and erosion over time can change landforms?

• The shorter and more rounded Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains.

• The Appalachian Mountains are composed mostly of sedimentary rocks while the Rocky Mountains also contain other rock types.

• The Appalachian Mountains are found in the eastern United States and the Rocky Mountains are found near the west coast.

• The length of the Appalachian chain is approximately 2,400 kilometers, and the Rocky Mountain chain is about twice as long.
