1. What happens to the sediment when a river slows down at a curve?

Why are sinkholes common in Florida?
Florida is a peninsula. Sinkholes are commonly formed on peninsulas because a peninsula is surrounded by water.
Florida has a lot of swamps with animals that burrow into the sandy soil making holes and tunnels that collapse.
Florida's underlying rock is limestone. Limestone dissolves easily, forming caverns which can then collapse and form a sinkhole.
Florida has a lot of oil underground. When the oil is removed, there is nothing left to hold up the soil
What process is responsible for sinkholes?
chemical weathering
earthquakes
volcanoes

Valley
Delta
Canyon

In the forest spotted owl make their home in the cavities of dead trees. The same habitat is home to rodents that owls feed on. Logging by humans have caused the population of owls to decline. What statement BEST explains the relationship between humans and the spotted owl.
humans have taken away resources needed by owls, so there are fewer owls.
Humans increased the available food for the owls, so there are more owls.
Humans eliminated predators of the owls, so the owls increased.
Humans moved the owls to the zoo, so there are less owls in the woods.
Increased human populations can lead to the depletion of of resources within communities. Compared to other communities, which of these resources is MOST likely to be depleted in desert communities?
gasoline
water
oxygen
minerals
It is estimated that half of the 10 million species of organisms on the planet live in the tropical rain forests. Deforestation of the rain forest causes the extinction of as many as 50,000 species per year. Clearing tropical rain forests causes the extinction of many species because

pollution caused by humans increases the greenhouse effect.
many unique habitats and ecosystems are being completely destroyed.
destruction of the rainforest contributes to the depletion of the ozone.
