Lab Exam 1 Review

Front

What causes warm water to float on top of cold water?

Back

Warm water is less dense than cold water.

Front

Which map projection is best for preserving direction for navigation?

Back

Mercator projection preserves direction.

Front

What effect does higher salinity have on water density?

Back

Higher salinity increases water density.

Front

What tool is used to measure orientation and direction?

Back

A compass is used to measure orientation and direction.

Front

Are satellite tags useful for identifying animal diet?

Back

False, satellite tags are not primarily used for identifying animal diet.

Front

Define density in the context of fluids.

Back

Density is the mass per unit volume of a substance.

Front

What is the principle behind the Mercator map projection?

Back

The Mercator projection distorts size but preserves angles, making it useful for navigation.

Front

How does temperature affect the density of water?

Back

Higher temperatures decrease the density of water.

Front

What is the role of a refractometer?

Back

A refractometer measures the refractive index of liquids, often used to determine salinity.

Front

Explain the concept of buoyancy.

Back

Buoyancy is the ability of an object to float in a fluid, determined by the density of the object compared to the fluid.
