Hey there! I'm happy to help!
The Earth is extremely ancient (approx. 4.6 billion years), so its milestones are going to have to be something huge and very grand in scope that has also happened a few times.
Changes in climate can be significant, but these are not as important of an event in Earth's history to mark the different eras. While changes in climate can lead to more drastic things, the changes on their own are not good enough of a definer.
Asteroid impacts are pretty huge, but it doesn't make sense to have each era be marked by an asteroid impact because it is an extremely specific type of event and it hasn't happened a large amount of times in Earth's history, so this isn't going to be the principal marker.
Old scientists in lab coats is just a play on words of the question. Obviously the paleontologists and geologists chose what to have define the different eras, but it isn't like the scientists themselves ARE the actual markers.
The eras of the geologic time scale are best defined by C. mass extinction events. Asteroid impacts were under the umbrella of this, and that is why it wasn't the right answer. This is a much more broad term that represents the times that Earth was completely changed whether that be from an asteroid, an ice age, a volcano eruption, etc. These are huge in scope and happened many times in the history of the Earth, so it makes to have these mark the different eras.

Hope it helps you.industries that process raw materials before being transported to the market
Hey there! I'm happy to help!
The industries that process raw materials before being transported to the market are manufacturing industries. This normally takes place in factories or processing areas.
For example, a factory might take metal that it is obtained from the Earth ( a raw material) and manufacture it into a steel beam.
Manufacturing is known as the secondary sector of the economy as it is essentially the second step in the process after raw resources (primary sector) are obtained.

What does ethically produced mean? Does this phrase apply to sweatshops
Hey there! I'm happy to help!
Ethically produced means that a product was produced or a service was completed in a moral way and without infringing on the rights of others.
This phrase does not apply to sweat shops. These were places with unsafe and poor working conditions where workers were worked to their max and received low wages. The leaders of these companies were so concerned about profits that they did not take into account the well being of their employees. This is definitely not ethical, so products produced in sweatshops were not ethically produced.

Hey there! I'm happy to help!
The topography of the Earth is all of the unique changes in landscape with the different formations, elevation changes, etc.
It appears that this question is talking about rivers because it mentions something that carries huge amounts of water. Rivers are a principal factor in the sculpting of the Earth's surface as water can erode rocks and transport the sediments to other locations.
Rivers take water and transport to the sea. The sea is basically the ending point of the rivers as there is no where else for it to go. It is at the lowest elevation, so the rivers can't really flow anywhere else now.

Why are neutrons an important part of nuclear fusion in the sun? (Hint: Think of Einstein's equation!) How can two protons become a proton and a neutron? (Remember what we learned the second week):
Explanation:
1 Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy. Einstein’s equation (E=mc2), which says in part that mass and energy can be converted into each other, explains why this process occurs. If scientists develop a way to harness energy from fusion in machines on Earth, it could be an important method of energy production.
2. A Hydrogen atom contains one Proton and zero Neutrons. When two Hydrogen nuclei collide, one of the Protons undergoes a type of radioactive decay called Beta-plus Decay, where a proton transforms into a neutron. This happens when there are too many protons in the nucleus, because the positive protons repel each other.

what is the distribution of power in legislative branch and executive branch in parliamentary and presidential governments
Explanation:
Defining characteristics of the parliamentary system are the supremacy of the legislative branch within the three functions of government—executive, legislative, and judicial—and blurring or merging of the executive and legislative functions. The legislative function is conducted through a unicameral (one-chamber) or bicameral (two-chamber) parliament composed of members accountable to the people they represent. A prime minister and the ministers of several executive departments of the government primarily carry out the executive function.

Which of the earth's spheres contains its plants and animals?
lithosphere
hydrosphere
biosphere
atmosphere
Hey there! I'm happy to help!
The lithosphere is all of the things under the Earth's surface. This includes some plants and animals, but not all of them.
The hydrosphere is all of the things in the water on Earth's surface. Once again, this includes many plants and animals, but not every single one.
The atmosphere is all of the things in the air or the sky of Earth. You guessed it, this includes many plants and animals, but not every single one.
The biosphere includes all living plants and animals on Earth's surface. The root word "bio" means life, so the biosphere is going to have to do with biology, biodiversity, biography (if you're a human), biochemistry, etc.

Hi
Answer:
BCA= 41
Explanation:
ABCD=180
DCA=26
ABC=113
BCA=?
ABC+BCA+DCA=180
113+BCA+26=180
139+BCA=180
BCA=180-139
BCA =41
Answer:
41°
Explanation:
I took the test and got it correct and other brain users confirmed it was correct.
I will list the steps on how to get the answer
Angle DCA is 26° and angle CAB is also 26° because alternate interior angles are equal.
the sum of the interior angle of a triangle is 180. So
∠CAB + ∠ABC + ∠BCA = 180°
26 + 113 + ∠BCA = 180
∠BCA = 180 - 139
∠BCA = 41°
in conclusion, the answer is 41°.
