In a population of rabbits, some have white fur while others have brown fur. Which fur color might be advantageous in a snowy environment, and why?

• White fur, because it provides camouflage in snow

• Brown fur, because it absorbs more sunlight

• White fur, because it attracts mates more easily

• Brown fur, because it is more visible to predators

Why might a trait become more common in a population over generations?

The US Army Corp of Engineers is concerned that the Mississippi River may jump its banks near point A during a big flood and form a new main channel much further to the west. If this were to occur, what would happen to the current river delta at point B over time?

• The delta would begin to shrink.

• The delta would become much larger.

• The size of the delta would remain about the same.

• The delta would have higher amounts of sand and silt.

If you looked at a map of the Earth from 100 million years ago, it would look much different than today. This is because:

• The continual circulation of magma underneath the Earth’s crust has caused the crustal regions to move.

• Life forms and organisms living on the Earth in the last 100 million years have caused the landscape to radically change.

• Erosion and weathering has changed the shape and location of the continents.

• Gravity forces from the Moon and Sun cause the continents to move.
