A student created a model of convection using a beaker, water, and food coloring.

The model did NOT demonstrate convection as the student had intended. The model could be improved to best demonstrate and model convection by adding a -

• light source

• heat source

• second food coloring

• wind source

Energy from the Sun is transferred from the Earth's surface to the atmosphere, resulting in atmospheric convection currents that produce winds. How do physical properties of air contribute to convection currents?

• The warmer air sinks because it is more dense than cooler air

• The warmer air rises because it is more dense than cooler air.

• The warmer air sinks because it is less dense than cooler air.

• The warmer air rises because it is less dense than cooler air.

The term El Niño in meteorology describes a prolonged warming period in the Pacific Ocean near the equator. The increase in surface temperature caused by El Niño can last up to two years.

What is the most likely effect of El Niño conditions?

• A decrease in severe storms originating from the Pacific Ocean

• An increase in hurricanes originating from the Pacific Ocean

• A decrease in precipitation along Pacific coastal regions

• An increase in stationary fronts developing along Pacific coastal regions

Scientists discovered trilobite fossils in Oklahoma and Morocco, as illustrated on the map below. Additional research in these areas shows that the rocks in Oklahoma and Morocco surrounding these fossils are physically and chemically similar. The discovery of trilobite fossils in Oklahoma and Morocco provide evidence of -

• plate tectonic movement

• volcanic eruptions

• weathering and erosion

• weathering and deposition

Students modeled the formation and weathering of a volcano in the ocean. The students drew a line around an aquarium to represent sea level. Clay was pushed through a hole in the bottom of the aquarium to represent the formation of the volcano. Students then cut sections of the clay, using a small wire, to represent weathering of the volcanic formation. Throughout the investigation, students took a series of pictures of their model.

What order of topographic maps best matches the order of the model pictures?

• 
•
