What effect does the sun have on surface water?
It causes it to boil
It causes it to rain
It causes it to sink
It causes it to evaporate
What can cause cracks in rocks or even sidewalks?
Snow melting
erosion
Ice wedging from water freezing
What is the turnover effect in lakes?
The process of water layers mixing due to temperature changes
The process of ice forming on the surface of the lake
The process of fish migrating to deeper waters
The process of algae blooming in the summer
During which season does lake turnover typically occur?
Only in Winter
Only in Summer
Summer and Winter
Spring and Fall
How does ice formation on a lake affect the turnover process?
It causes turnover to happen continuously
It has no effect on the turnover process
It accelerates turnover by cooling the water
It prevents turnover by insulating the water below
Why does ice float on water?
Because it is less dense than water
Because it is heavier than water
Because it is the same density as water
Because it is denser than water
How does the formation of ice on the surface of a lake benefit aquatic life?
It allows more sunlight to penetrate
It increases the water's salinity
It provides more oxygen
It insulates the water below, maintaining a stable temperature
What happens to the density of water as it freezes?
It becomes zero
It remains the same
It decreases
It increases
What happens to the mass of water when it changes from liquid to gas?
It becomes zero
It increases
It decreases
It remains the same
How does the density of water change as it transitions from liquid to solid?
It becomes zero
It remains the same
It decreases
It increases
