Pot holes are cracks or weaknesses in roads. If there is a crack/crevice in the road then water may enter and freeze over night, expanding the crevice. As this process repeats and the road is used more then the pot hole will expand in size.

DO NOT ATTEMPT ALONE! YOU'LL NEED AN ADULT TO ASSIST YOU IN THIS PROJECT!Child's pinwheelAluminum foilEmpty soup can or similar sized tin can with one end cut offA wooden rulerSmall cooking potHot plateHammer10p nailTape or rubber bandsMitten type of pot holderTake hammer and nail and carefully punch a hole in the end of the tin can near the edge. Punch another whole directly across the top from it. The two holes should not be bigger than 1/8 inch across.Tape or attach the ruler to can with rubber bands.Put water into the pot and cover the top of the pot with two layers of tin foil. Tightly crimp the tin foil around the edges so it seals the top tightly.Using the nail, punch a hole in the top of the tin foil cover in the very center about 1/16 inch across. Put covered pot to side.Put the pot onto the hot plate and bring to a boil.Put on the mitten pot holder, and when steam starts coming out of the top, carefully hold the pinwheel over the one hole. Notice how fast the wheel spins.Take the can on the ruler and place it on the top of the pot so that the hole is in the center of the open end of the can. Steam should now be coming out of the top of the can through the two holes.Carefully hold the pinwheel. Turn the pinwheel so that the holes are on opposite sides of the pinwheel. Notice how fast the pinwheel turns.Take pot off the hot plate and let cool. Carefully take off the tin foil, add more water to the pot and put tin foil top back on. Take the nail and poke lots of holes all over the tin foil. Punch 5 holes close to the edge away from the center hole, repeat the experiment with ten holes around the edge, 20 holes around the edge.Bring the pot back up to boiling. Hold the pinwheel over only the one center hole. How much steam do you see? How fast is the pinwheel turning?With one hole the pinwheel, how fast did the pinwheel turn? With the can making the steam hit the wheel equally on either side, what happened? When you punched more holes in the tin foil what happened?In a geothermal power plant, steam is used to turn a turbine. The turbine is attached to a generator to make electricity. There are two places in the world where natural steam is found under ground and is used to make electricity. One is in Italy. The other is north of San Francisco in an area called The Geysers. The Geysers produces enough energy to power a city of about one million people. But in recent years, the amount of steam produced by the area has decreased. Some people think that it's because there are too many "holes" in the ground like the pot cover with 20 holes. It's like having a soda with 20 straws in it and all of your friends and you sipping at the same time. The soda glass will be drained VERY fast. That's what some people think is happening to the Geysers…that it's running out of steam.
What are the causes of landform development on the Earth?
Techtonic plate movement, weathering and degradation and human intervention (farming, civilisation).
Why is the water in the earth pot cool?
Earthen pot has tiny pores on its surface. The water oozes out from these pores. It then evaporates taking energy known as "latent heat" from the pot. Thus, the temperature of the water inside decreases. This process goes on and this is the reason why the water in earthen pot is cooled faster.
