This is an environmental change.
The plant is polluted soil will not grow as well and will most likely die.
You have two pieces of the same material. One is heavy and the other is lighter.
Which will require more energy to heat up to 150 degrees, and why?
The heavier one.
The heavier material has more mass which means it has more particles. Since there are more particles than the lighter object it takes more energy to heat up a greater number of particles.
We looked at a claim to try to explain what is causing climate change. One of them was greenhouse gases emitted by humans and other sources.
