ANSWER: ice wedging, also known as freeze-thaw weathering
Answer:
See the explanation below, please.
Explanation:
Isotopes correspond to atoms with the same atomic number (Z) but different mass numbers (A), that is, they differ in the number of neutrons. Ex Carbon 14 and Carbon 12, Hydrogen and Deuterium.
Isotopes can be determined using the mass spectrometry technique, measuring the relative abundance of each ion (gives us the m / z, ratio between mass and charge).
Answer:
B
Explanation:
As you move from left to right, the number of protons increases. More protons means a bigger positive charge to pull in the electrons from the shells. This would then decrease the size of the atom.
Thus, the answer is B, the size decreases.

Option "A" is the correct answer.
Texas produces more crude oil than any other state in the Union. Texas has 27 petroleum refineries with a total capacity of more than 5.1 million barrels of oil per day. Daily production of refined oil makes up 29% of the united State's refining capacity.
Texas and oil are synonymous. In 2006, the oil industry employed 3.1 percent of the state's workforce and produced $ 30.6 billion in earned income.
The oil drilled in Texas is used for everything from vehicle fuel to heating homes. Most of the oil in Texas is produced through drilling which differs from the tar-sand production of Alaska where the oil is closer to the surface.
