In a particular region, a change in climate would likely have a greater effect on organisms than a change in weather would. Which of the following statements best explains why?

• A change in climate causes more earthquakes than a change in weather does.

• A change in climate causes clouds to form faster than a change in weather does.

• A change in climate affects the number of daylight hours more than a change in weather does.

• A change in climate affects an environment for a longer time than a change in weather does.

What is the initial source for global winds and convection in the atmosphere?

• unequal heating of the Earth by the Sun

• the rotation of Earth

• the moon’s gravity

• continental
