On a hiking trip, you see a large tree root has grown into the cracks of a rock and caused it to break apart. this is an example of mechanical weathering chemical weathering hydrologic weathering oxidative weathering

i believe the answer is true.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
