btw: you do not have to answer all of the questions if you don't want !

Can't help you on 1-4...I'm not very good with energy transformations.
5. coal, oil/petroleum, natural gas; water, wind, plant (there's a name for energy sources coming from plants, but I can't remember it)
6. Metals are lustrous, malleable, and good conductors of heat. Nonmetals are dull, brittle, and poor conductors of heat.
7. Crust is solid, mantle is solid, outer core is liquid, inner core is solid.
8. Millimeters, centimeters, meters, kilometers, milliliters, liters...that's all I can think of.
9. Gravity is the force that pulls objects towards the center of something. Earth's gravity keeps us all on the ground.
10. Anything that causes an object to move.
11. Mass is how much stuff is in something; weight is how heavy something is.
12. Pangaea
13. It's the biggest celestial body in our solar system.
14. A comet is gas and dust that shoot through the sky. (I'm really not sure; I just know it's made of gas and dust)
15. ???
16. ??? 
17. Insurgent and Allegiant plates xD Divergent plates can form subduction zones and rift valleys.
18. about 5 billion years
19. hydrogen and helium

2) Nuclear fusion
3) Chemical energy - electrical energy - light energy
4) Heat energy-mechanical energy-kinetic energy
5) Fossil fuels like coal, petroleum and natural gas
6) Metals : sonorous, ductile Non metals : brittle, non-lustrous
7) Solid liquid, gas
8) Metre, grams, litres, degrees etc.
9) The force the earth exerts in its gravitational field.
10) A force is directly proportional to acceleration
11) Mass is the amount of matter contained in a body and weight  is the force which a huge mass ( like that  of sun) exerts on a mass.
12) Eurasia
13) It is because the sun has a huge mass ( Gravitational force is directly proportional to difference in mass)
14) Comet is a celestial object of a solar system that orbits the sun. It is not like plamtes, has a comparaitively less mass and orbits are long.
15) It depends on the distance ( directly proportional)
19) Dust, heat, hydrogen and helium.

Replicate prove reliability and validity

The net force is 100
