Wind is A.
two air masses meeting
B.
air in motion
C.
a high pressure area
D.
a low pressure area

B makes the most sense because wind is constantly moving, and you can also use process of elimination. Wind has no pressure it’s only speed, so knock those out. Two air masses meeting would mean that they may have equal speeds against each other not really causing movement so it would be B. Hope this helps <3

B) Rocks are an abiotic factor because they have never been alive.

An abiotic factor is a non-living component of the ecosystem. The abiotic factor affects the living factors of the ecosystem. The abiotic factors includes sunlight, weather conditions, temperature, water, soil, minerals and other factors.

Rock is a non-living factor of the city park ecosystem. Therefore, statement rocks are an abiotic factor because they have never been alive best illustrates  a abiotic factor that is often found in a city park.
