how is weather different from climate?
weather is the average atmospheric conditions over a long period of time. climate is the current conditions of the atmosphere.
weather is current conditions of the atmosphere. climate is the average atmospheric conditions over a long period of time.
weather can fluctuate daily. climate is the same over a short - period of time.
weather is the same over a short - period of time. climate can fluctuate daily.

Explanation:

First Question: How is weather different from climate?

To determine the correct answer, we recall the definitions of weather and climate. Weather refers to the current or short - term (e.g., daily) atmospheric conditions like temperature, precipitation, etc. Climate, on the other hand, is the long - term average of these atmospheric conditions over a period of years, decades, or more.

• The first option swaps the definitions of weather and climate, so it's incorrect.
• The second option correctly states that weather is the current conditions of the atmosphere and climate is the average atmospheric conditions over a long period of time.
• The third option is wrong because climate is not the same over a short period; it's a long - term average.
• The fourth option is incorrect as it misrepresents both weather (which can fluctuate daily) and climate (which is a long - term pattern, not daily - fluctuating).

The Earth's energy budget is about the balance between the energy the Earth absorbs (from the Sun) and the energy it radiates back to space as heat. It is calculated as the amount of sunlight Earth absorbs minus the amount it radiates to space as heat (to show if there is a surplus or deficit, but the basic definition of the budget in terms of the relationship between absorption and radiation is absorption minus radiation).

• The first option, "How much sunlight Earth absorbs minus how much it radiates to space as heat", correctly represents the Earth's energy budget concept.
• The second option (plus) is incorrect as we are looking at the balance (net) between absorption and emission, not the sum.
• The third option (times) and the fourth option (divided by) do not represent the energy budget concept, which is about the balance (difference) between incoming and outgoing energy.

Global climate refers to the long - term behavior of measurable factors (like temperature, air pressure, etc.) across the entire Earth. Regional climate is the long - term behavior of these factors over a specific geographic region.

• The first option, "Long - term behavior of measurable factors such as temperature, air pressure, precipitation, soil moisture, water runoff, cloud cover, storm activity, winds and ocean currents linked over the entire Earth", correctly defines global climate (long - term, entire Earth).
• The second option defines regional climate (specific geographic region), not global.
• The third and fourth options are incorrect because climate (both global and regional) is a long - term, not short - term, behavior.

Answer:

B. Weather is current conditions of the atmosphere. Climate is the average atmospheric conditions over a long period of time.
