Which of these is not an internal factor which affects the global climate?

decrease in the Sun's energy
warm and cold ocean currents
increase in atmospheric carbon dioxide
release of dust during volcanic eruption

How can variations in the rate of interaction between the hydrosphere and the atmosphere result in global climate change?

by causing droughts and floods
by producing more greenhouse gases
by changing the amount of water on Earth
by decreasing the atmospheric temperature

What would people living along the coast in South Florida do if there was a hurricane warning?

move to locations away from the water
flock along coasts to watch the natural phenomenon
buy instruments to predict the exact location of the hurricane
measure water levels to know the exact time of the hurricane
Which of these statements best describes an interaction between the atmosphere, hydrosphere and biosphere?

Strong winds blow over a lake and create ripples.
A river flows downhill at a very high speed and uproots trees.
The magma flowing out of a volcano blocks the movement of a river.
A hurricane carries ocean water across the coast and damages houses of people.

Global climate patterns are dynamic: They are continually changing in response to solar radiation, atmospheric greenhouse gas concentrations, and other climate forcing factors. Among the more predictable of these changes are cyclical changes in solar radiation reaching the poles.

B. by producing more greenhouse gases

A reasonable hypothesis is that any average global temperature increases due to increased atmospheric concentrations of global greenhouse gases will lead to some increase in the rate and amount of melting of polar ice and glaciers.

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres. Such changes that take place within an ecosystem are referred to as events
