(b) Pressure increases
(c) Dew Point temperature is often reached
(d) Temperature decreases

Answers

Answer: B

Explanation:

As you go up in elevation, the amount of “air” pressing down on you lessens. Think of standing at the base of a mountain in an invisible tube. The tube is filled with “air” pressing down on you. Now imagine that you are in that same tube but at the top of the mountain. The “air” in the tube above you is less, meaning less pressure pushing down on you.

What is federal style of government?

Federalism is a form of government in which two levels of authority share control over the same region. Larger territorial areas are typically governed more broadly by an overarching national government, while local concerns are handled by smaller subdivisions, states, and cities.

A strong central government shares power with states or provinces that have significant self-governance, typically through their own legislatures. Examples include the Federal Republic of Germany, Australia, and the United States.

Some characteristics include: A distinct division of powers between the federal government and the states; An independent judiciary; A bipartisan legislature; A system of dual government; and Constitutional supremacy.

Thus, option B and D are correct.

In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.

Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.

an asteroid impact likely caused a mass extinction at the end of the Cretaceous.

A.
Both peoples stayed in the regions they had settled for centuries.
B.
The two kingdoms had close trade relations for centuries.
C.
Both peoples had originally migrated from the same region.
D.
The two kingdoms both were originally controlled by Assyria.

Answers

Answer:

The two kingdoms had close trade relations for centuries.

Explanation:

The kingdoms of Egypt and Kush, even before becoming part of a single kingdom, were very similar to each other. For starters, they were bordering each other, with Egypt being located in the lower part of the Nile, while Kush being located in the central part of the Nile. Because they were bordering and had societies that revolved around the same resources, they had similarities even from the beginnings of these civilizations.

Over time, these two kingdoms developed very close ties. The trade between the two was immense, and people from both kingdoms were regularly traveling between the two. This brought in exchange of cultural traits, ideas, and technology, and gradually the two kingdoms were becoming more and more similar to each other, so even when the time came when they entered a conflict and Kush fell under Egyptian rule, there wasn't any particular problem for the population as almost everything remained the same.
