FY23 AMS Semester Exam Review (Ch. 1-3)

Front

What type of tide occurs when the Earth, Moon, and Sun are at right angles to each other?

Back

Neap tide

Front

As temperature increases, what happens to the solubility of most solids in water?

Back

Decreases

Front

What geological process involves molten material rising from the mantle and creating new oceanic crust?

Back

Sea-floor spreading

Front

At what depth does the thermocline typically begin in ocean water?

Back

Approximately 75 m

Front

What is the most common ionic compound found in seawater?

Back

Sodium Chloride

Front

Define 'thermocline' in the context of oceanography.

Back

A layer in a body of water where the temperature changes rapidly with depth.

Front

What is the primary cause of tides on Earth?

Back

The gravitational pull of the Moon and the Sun.

Front

Explain the difference between spring tides and neap tides.

Back

Spring tides occur during full and new moons when the gravitational forces are aligned, while neap tides occur during the first and third quarters of the moon when the forces are perpendicular.

Front

What is the role of mid-ocean ridges in plate tectonics?

Back

They are sites of sea-floor spreading where new oceanic crust is formed.

Front

What is the significance of sodium chloride in seawater?

Back

It is the most abundant dissolved salt and plays a crucial role in ocean chemistry.
