Sci 8 - Earth Science ILS Review HW #1

The map below shows latitude and longitude lines for a portion of North America. Points A and B represent two cities.

Compared to the location of city A, the location of city B is at

• the same latitude, but a different longitude

• the same latitude and same longitude

• a different latitude and the same longitude

• a different latitude and different longitude

The diagram below represents a portion of Earth’s latitude/longitude system. A and B are locations on Earth’s surface. The arrows show the direction of Earth’s rotation. If it is noon at location A, then at location B it is

• morning

• noon

• afternoon

• midnight

Which geologic process occurs when the acid in precipitation dissolves certain types of rock?

• faulting

• tilting

• weathering

• erupting

The map below shows dark bands that indicate long mountain ranges on the west coasts of North America and South America.

What caused the formation of these mountain ranges?

• erosion of continental coastlines by ocean waves

• deposition of river sediments entering the ocean

• collision of lithospheric tectonic plates

• uneven heating of Earth’s surface

Scientists have discovered fossils of the same organisms in many different parts of the world. These fossils provide evidence that

• the continents were once joined together

• most life-forms that existed in the past are still present today

• most of Earth’s surface was once covered by molten rock

• rocks have been transformed from one type to another

Volcanic eruptions are caused primarily by the movement of

• rock by erosion

• Earth in its orbit

• planetary winds

• tectonic plates

Earth’s hydrosphere is a layer of

• rock

• air

• lava

• water

The map below shows the current positions of South America and Africa. Points A and B represent areas on the two continents where scientists have discovered fossils of the same animal species. How does the Theory of Plate Tectonics explain the location of these fossils?

• The continents were once joined together.

• The animals were able to swim from one continent to the other.

• Humans transported the animals from point A to point B.

• The animals developed independently on both continents.

Which diagram represents a chemical reaction used to identify a mineral?

• 1

• 2

• 3

• 4

The diagram below represents how rock is affected when water enters cracks in rock, freezes, and becomes ice. Which geologic process is represented in the diagram?

• faulting

• weathering

• metamorphism

• volcanism
