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.
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.
C.
meteorites and other space debris no longer contain the metal iridium.

Why does a small percentage of the country's population live in China's West?

Answers

While China's population has held steady through that time, the economic growth has driven people from the country's interior farmland to the coast, and the combination of industrialization and a swelling coastal population is taking its toll on the marine environment, according to the researchers.

Due to unfavorable climate and soil for farming and production, Western China is not conducive to living. Due to this, China's western regions are sparsely populated compared to other parts of China, where production and farming are more conducive.

The eastern, coastal provinces are much more densely populated than the western interior because of the historical access to water.

As an air mass rises in the troposphere, which of the following DOES NOT happen?
(a) Pressure decreases
(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.
