Answer:
Leaf shapes on rocks are caused by leaves becoming fossilized.
Explanation:
When leaves are fossilized, like bones, they leave an imprint on the rock.

The amount of heat required that is used to change 1l of water into vapour at atmospheric pressure is known as latent heat of vaporisation
Answer:
There are two explanations to this: covalent network bonding and carbon-silicate cycle.
Explanation:
A network solid or covalent network solid is a chemical compound which is formed through a continued network of atoms or molecules held together by a covalent bond throughout the system. An example included C-C bond in graphite or C-Si bond in silicon carbide (tentative reaction equation below):
xSiO2 + yCO2→ SixCyO(2x+2y)
Si-Si bonds are not as strong as C-C bonds and can easily be displaced as the particles react with atmospheric CO2.
The second scenerio is when silicates such as calcium silicate CaSiO3, or wollastonite, reacts with atmospheric carbon dioxide and water to yield a calcium ion, Ca2+, a bicarbonate ion, HCO3-, and dissolved silica. This process occurs during carbon-silicate cycle and increase organic carbon content:
2CO2 + H2) + CaSiO3 → + SiO2CaCO3 + CO2 + H2)
Answer:
D - water changes from a
Explanation:
You're correct!
We are asked what happens when the pressure changes from 0 atm to 10 atm at 0C.
If we look at the graph at 0C on the x axis and at 0 atm on the y axis, we can see we are in the yellow area of the graph, so the water starts at a gas.
If we keep the temperature the same, but change the pressure to 10 atm (much higher on the y axis) we are in the blue area, so the water is now a liquid. Therefore, D is correct
