Explain how water freezing and thawing causes weathering and the type of weathering it would be considered.

Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. Freeze-thaw occurs when water continually sleeps into cracks, freezes and expands, eventually breaking the rock apart.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
