2 and 4 are wrong.

Although this is not my area of expertise, those last choices sound better.

2 n 4 wrong

2 and 4 wrong

To answer these questions, we need to understand how air masses form and their characteristics.

1. Air masses that form over land would be mostly:
When air masses form over land, the surface heating causes the air to become warm. So, the correct answer is A. Warm.

2. Air masses that form over oceans or seas would be mostly:
Water bodies like oceans or seas have a moderating effect on the air temperature, causing the air masses above them to become warm. So, the correct answer is A. Warm.

3. Air masses that form over northern locations would be mostly:
Northern locations are generally characterized by colder climates. When air masses form over these regions, they tend to be cold due to the low temperatures in these areas. So, the correct answer is B. Cold.

4. Air masses that form over tropical regions would be mostly:
Tropical regions are known for their warm climates, so air masses that form over these areas would also be warm in nature. So, the correct answer is A. Warm.

In summary:
1. Air masses that form over land are mostly warm.
2. Air masses that form over oceans or seas are mostly warm.
3. Air masses that form over northern locations are mostly cold.
4. Air masses that form over tropical regions are mostly warm.

Would 2 be wet and 4 be warm?
