Law of superposition

Principle of cross-cutting

Explanation:

The geologic precepts that would be used to determine the relative ages of the rock strata are the law of superposition of strata and the principle of cross-cutting.

  • The law of superposition of strata states that "in an undisturbed sequence of rock strata, the oldest layer is usually at the bottom and the youngest on top".
  • From this law we understand that the oldest layer will be at the bottom if the rock has not been disturbed.
  • Here the rock has been disturbed by folding and we need to unravel to fold and see how the rock sequence originally was laid.

The principle of cross-cutting states that "faults are younger than the rocks they cut through". Structures in rocks are younger than rock layers they cut through.

A fault or joint will only pass through a rock that has been formed before it occurred. Subsequent rocks will be younger than the fault.

Sugar is a covalently linked compound with many atoms. Water is able to dissolve sugar. What does this suggest about the atoms o
luda_lava [24]

Answer:

When you put sugar inside of a cup with water, the sugar is still visible because it's molecules have just gotten in touch with water molecules. The sugar molecules are still attracted to each other but as you stir it, it seems to disappear but not completely. When the water is stirred sugar mix with water and water molecules place themselves between the sugar ones.

Conclusion: It suggests that the sugar molecules are more attracted to water molecules which is why they easily separate from each other.

. Why a chlorine atom with an atomic number of 17 will be negatively charged when its valance shell gains an electron.
sesenic [268]

Explanation:

When chlorine bonds and becomes stable, (had a full outer electron shell), because we know that chlorine has 7 electrons in it’s outer shell, it requires 1 to gain noble gas structure. So, when if bonds with an element and then becomes stable, the gaining of an electron means it becomes a negatively charged ion. (an ion being a charged particle.)
