Since light passes through water, why can't you see to the bottom of a very deep clear pool?
Tuesday
Acid rain is a pollution problem that has grown worse in the last 30 years. How does the automobile contribute to this problem?
Wednesday
Why do pencils and diamonds have in common?
Thursday

Monday:
It takes energy to push light through water so it loses energy the deeper it gets until it can't go any deeper.
Tuesday:
Acid rain is rain with a low ph automobile help the build up gases and bad material. Acid rain can destroy forest and kill animal.
Wednesday:
they're both made of carbon atoms. But in a different in molecules build.
Thursday:
Styrofoam absorbs heat so a cold drink's temperature won't change any noticeable amount.
Friday:
Chocolate no matter what country your in there is a place selling or making chocolate.

Monday:
You can't see the bottom of a very deep clear pool because light takes energy to passes through water then the pool lose some of its energy and it gets hard and harder to see the bottom even if the pool or the water is clear
Tuesday:
Automobile has a great contribution towards the modern life. Today’s modern life use to be impossible without contribution of automobile because it gives the automation to modern life, makes our distance very closer and moreover today’s automobile is very safe day to day life.
Wednesday:
A pencils and diamonds both have Carbon Atoms in it
Thursday:
The Styrofoam has a high resistance to heat transfer that heat does not "flow" through it very easily. Therefore,the heat from the outside air does not enter the container very quickly
Friday:
Bread is the world’s most widely eaten food and it has been part of our diet since the early times of mankind.

Monday
You can't see the bottom of a very deep, but clear pool, because the light is slowly absorbed by water molecules and impurities.
Tuesday
It causes harmful gases that get absorbed by the air causing acid rain.
Wednesday
They both have Carbon Atoms.
Thursday
It has a high resistance to heat transfer. Heat doesn't flow through it very easily. This happens because styrofoam consists of expanded polystyrene.
Friday
The most widely eaten food is rice, because almost everyone in the world eats rice. Every country is Asia eats rice too.
