I am sorry to be the bearer of bad news but most of these questions are things we learned in 9th grade. Many others are coming from a false premise. And some are really hard to understand, so I dont know what you are asking.

Energy topic: Gravity and momentum are big factors in our solar system. Most other questions can be answered from Wikipedia or a basic textbook.

Magnets: textbook 101 magnetism

Sun: The sun has fusion. Distance from sun affects radiation.

Atmosphere: gravity and 101 textbooks :)

Water: mostly unclear, but I suggest you check 101 textbooks and leverage forces are strong.

Rivers: Citation needed. Trees are strong, roots are strong. Water follows the easy path most likely.

Sea: poles are further away from the sun. Exchange of heat happens but does not resolve distance, so it balances to what we have.

Blood: citation neaded. Human body textbook. National geographics.

Tree: trees have no heart and no blood.

That should give you hints where to look 😅
