Unit 3 Assessment Review

The list describes one of Earth's layers. The list is describing: - Composed of iron and nickel - Contains both liquid and solid parts - Extremely hot

• the core because strong pressure and temperature create both liquid and solid parts.

• the core because weak pressure and temperature create a hot environment.

• the mantle because strong pressure and temperature create a hot environment.

• the mantle because weak pressure and temperature create both liquid and solid parts.

The diagram shows the layers of Earth. Which statement best describes Layer 1 and Layer 2?

• Layer 1 is the inner core and is solid. Layer 2 is the outer core and is liquid.

• Layer 1 is the outer core and is liquid. Layer 2 is the inner core and is solid.

• Layer 1 is the inner core and is not hot. Layer 2 is the outer core and is very hot.

• Layer 1 is the outer core and is not dense. Layer 2 is the inner core and is very dense.

A scientist studied plant fossils she found in layers of earth in a mountainside. She put her findings in the table below. Which changes in the environment most likely explain the different fossils?

• The area went from being very hot, to being cool, to being very cold over time.

• The area went from being very hot, to being moist, to being very dry over time.

• The area went from being cold, to being underwater, to being very dry over time.

• The area went from being dry, to being very cold, to being underwater over time.

What would most likely happen if the temperature in the mantle decreased?

• The convection currents would slow down and tectonic plate movement would decrease.

• The density of the mantle would decrease and tectonic plate movement would slow down.

• The convection currents would speed up and tectonic plate movement would increase.

• The density of the mantle would increase and tectonic plate movement would slow down.

The picture shows a diagram of Earth's layers. What kind of activity is most likely at point X?

• massive storms, as the weak crust allows heat to spread from the mantle to the atmosphere and increase ocean temperatures

• strong drought, as the movement of material under the crust heats the waterways on the surface, causing them to evaporate

• earthquakes and volcanoes, as convection in the magma beneath the crust pulls the plates against each other

• the formation of large valleys, as the rotation of Earth about its axis causes a downward pull on the plates

The map below shows the location of Devon Island. Devon Island is located in a polar region. Scientists have discovered fossils of corals on Devon Island at Locations 1 and 2 shown on the map. Corals are ocean organisms that can only survive in warm waters. Which claim is BEST supported by the coral fossil evidence collected by scientists on Devon Island?

• Devon Island was once part of the surrounding landmass of Canada.

• The ocean waters surrounding Devon Island were once warmer than they are today.

• Devon Island was once part of the surrounding landmass of Greenland.

• The ocean waters surrounding Devon Island were once cooler than they are today.

A scientist cut into the side of a hill to study the layers of earth. In the lower layers, she found fossils of plants with long, deep root bases. In the upper layers, she found fossils of plants with wide, shallow roots bases. Which conclusion most likely explains the differences in the fossils?

• The animals that ate the plants in the area changed over time periods.

• The amount of rainfall that the area received changed over time periods.

• The number of plants in the population changed over time periods.

• The type of flowers that the plants produced changed over time periods.

Limestone can be found at the top of the Himalayas, the highest mountain range in the world. Limestone is a rock that usually forms at the bottom of shallow, warm waters. What does this information show about Earth?

• It shows that Earth circulates its minerals so often that they are forced up to the peaks of mountains.

• It shows that Earth has not changed much over the years, as limestone still remains on mountain peaks.

• It shows that Earth has evolved over time, as areas of land that had once been covered in water no longer are.

• It shows that Earth has mostly convergent plate boundaries that push limestone from the ocean floor to the top of mountains.
