1. Crystallization. Magma cools either underground or on the surface and hardens into an igneous rock.
2. weathering and erosion
3. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.
4. Rock Melting.
Metamorphic rocks underground melt to become magma. If you need more help https://www.ck12.org/earth-science/rock-cycle-processes/lesson/Rocks-and-Processes-of-the-Rock-Cycle-HS-ES/
Answer:
A normal atom has a neutral charge. When you are missing electrons it has a positive charge. When you have extra electron, you have a negative charge. I am not sure what the answer to your second question is, sorry.
Explanation:
Missing question:
A. All carbon atoms are identical.
B. An oxygen atom combines with 1.5 hydrogen atoms to form a water molecule.
C. Two oxygen atoms combine with a carbon atom to form a carbon dioxide molecule.
D. The formation of a compound often involves the destruction of one or more atoms.
Answer is: B and D.
A is correct because Daltan stated: All atoms of a given element have the same mass and other properties that distinguish them from the atoms of other elements.
C is correct because atoms combine in simple, whole- number ratios to form compounds, B is incorrect because ratio is not simple, whole number.
D is incorrect because according to Dalton. atoms can't be created or destroyed.
I think you were doing it right. Just find something in your kitchen and google the chemical formula. And from that you can see the elements in it. For example:
Salt, NaCl, Sodium and Chlorine.
Baking Soda, NaHCO3, Sodium, Hydrogen, Carbon and Oxygen.
Vinegar, CH3COOH, Carbon, Hydrogen and Oxygen
