Which explanation accurately describes convection within the ocean?

• Earth's mantle heats water at the bottom of the ocean, causing the water to rise toward the surface. The air at the surface cools the water, causing the water to sink

• Water near the ocean' surface is heated by air, causing it to sink toward the bottom of the ocean. As the water cools it sinks, causing it to rise back toward the surface

• Water near the equator is warmer because of direct sunlight. Water near the poles is cold and dense. Warm water moves toward the poles and cold water moves toward the equator

• The sun heats the surface of the water. The deeper the water, the colder it becomes. Warm water sinks and cold water rises

Which star has the lowest temperature?

• A
• B
• C
• D

What type of star is our sun according to the HR diagram?

• White Dwarf

• Red Dwarf

• Red Giant

• Main Sequence

A new star cluster is discovered, and its brightest main sequence star is a blue giant. What does this reveal about the cluster's age and development?

• The cluster is old, as blue giants are long-lived stars.

• The cluster is young, as blue giants burn out quickly.

• The cluster has stopped forming stars.

• The cluster is nearing the end of its life cycle.

Answer explanation

The presence of a blue giant indicates the cluster is young, as these stars have short lifespans and burn out quickly. An old cluster would not have bright blue giants, as they would have already evolved into later stages.
