Hey there! I'm happy to help!
We are looking for something that takes a long time to heat up due to a certain property, therefore affecting the weather.
FIRST BLANK CHOICE
The temperature of the land is a result, of the weather, not a cause, so this is not the correct option.
The temperature of the water does not really affect the weather. If the water in your city is cold instead of hot that will not cause the weather to be much different.
However, air is what mainly causes the weather. Air pressure fluctuations can cause certain storms and air is the driving factor of weather. Therefore, the first answer is air.
SECOND BLANK CHOICE
One of the options is specific heat. The actual fill in the blank is that is is harder for the air to heat up because of _______. Putting heat in there makes no sense. It's harder for the air to heat up because of specific heat? This is not the right choice.
The volume of the air is how much space it takes up, and air is basically everywhere, so this is not the correct choice.
The last option is density, or how thick the air is, usually due to how much water there is. This makes sense because if it is very thick you have to have more heat to get through all of the density. It would take longer to warm up a car filled with 20 people than with one person. Therefore, the second option is density.
Have a wonderful day! :D
