The answer would be B because you can go and find evidence and facts to conduct an investigation on that.
Answer: Getting into the technicalities, the continental crust has a density of around 3.0 g/cm3 compared to 2.6 g/cm3 of the continental crust. In addition, the continental crust is much thicker than the oceanic crust.

Explanation:
Electrovalent is a word often associated with chemical bonding in the field of chemistry. It is special type of bond that occurs between metals and non-metals.
These bond types are interatomic interactions occurring between two atoms to ensure that they attain stable configurations.
- This bond type is also known as ionic bonds.
- It occurs between two species with a large electronegative diffference i.e one specie is electropositive and the other highly electronegative.
- The more electropositive specie is metal and it readily loses its valence electrons.
- The electronegative non-metal gains the electrons and becomes negatively charged.
- The electrostatic attraction between the metal and non-metals yields the electrovalent bonds.
Answer: With the cold front, warm air is rapidly forced upward (like the shavings) in advance of the actual front (the “cutter”), creating towering cumulus clouds, some hard showers and quite possibly a few gusty thunderstorms followed by a push of cooler and drier air in its wake.
Explanation:
Answer:
- 20 J
Explanation:
Heat of Reaction = Heat of Products - Heat of Reactants
From the graph;
Heat of Products = 10
Heat of Reactants = 30
Heat of Reaction = 10 - 30 = -20 J
