The correct answers are:
- plates moving;
- breaking rocks;
- movement bellow the surface;
The earthquakes are a direct result of the plate tectonics. In order for an earthquake to appear, there should be a geologic activity caused by the movement of the tectonic plates. The movement of the tectonic plates causes a lot of pressure on the rocks. The rocks eventually break at certain places under the pressure. A they break, there's movement bellow the surface, or rather inside the crust, also referred to as adjustment. That movement and the release of power from it, causes lot of strong vibrations. The vibrations spread out and start shaking the ground in the surrounding area, which is actually the earthquake itself.
Answer:
- plates moving
- breaking rocks
- movement bellow the surface
B. conducts electricity
C. attracted to a magnet
D. high melting point
Answer: The correct answer option (A).
Explanation:
Chemical properties are the properties which are observed in a chemical reaction like change in arrangement in atoms or change in identity of the substance.
Metals reacts with acid to form salts and hydrogen gas. In which chemical composition of pure metal changes during the chemical reaction. So, yes it is a chemical property of metals.
Whereas conducting electricity, property to get attracted by magnet and high melting point doesn't changes the arrangement of an atoms which means they are not chemical properties of metals but are physical properties of metal.
Hence, the correct answer option (A).
answer is react to acid
