Today's fossil fuels began forming 300 million years ago. What allowed the process to begin?
A Mammals ate all of the plants
B Rainfall eroded huge mountains
C Dinosaurs roamed the land
D Many huge plants grew, died, and decayed
Think about which one of those processes can result in formation of fuel from the dead plant and/or animal material.
How does chlorophyll make a leaf look green?
im just in 5th grade. please explain again.

Ok.. you know what fossil fuels are, right? and what they're made of?
Then would plants being eaten eventually make a fossil fuel? just go down the line until you find one of them that work.
chlorophyll absorbs the colors of light it needs to function, the ones it does not need it reflects. which 2 colors do you think these are?
red and vioilet
D many huge plants grew, died, and decayed
For the first question, the correct answer is D - Many huge plants grew, died, and decayed. Fossil fuels such as coal, oil, and natural gas are formed from the remains of ancient plants and animals that lived millions of years ago. Over time, the dead plant and animal material gets buried under layers of sediment and undergoes a process called decomposition. This process involves the breakdown of organic matter by bacteria and fungi. As the material gets buried deeper, the pressure and heat increase, causing the organic matter to transform into fossil fuels.
Now, let's talk about why a leaf appears green due to chlorophyll. Chlorophyll is a pigment found in the chloroplasts of plant cells. It is the main pigment responsible for absorbing sunlight and converting it into energy through the process of photosynthesis.
Chlorophyll molecules absorb light energy most efficiently in the blue and red parts of the electromagnetic spectrum. However, they reflect or transmit the green light, giving leaves their characteristic green color. This is because the energy from green light is not as efficiently absorbed by chlorophyll, so it is not needed for photosynthesis and is reflected back.
It's great that you're in the 5th grade and asking these questions! If you have any more doubts or need further explanations, feel free to ask.
