HOW DOES ALTITUDE AFFECT YOUR BREATHING?
Answer:
In higher altitudes, the air is usually colder, less dense, and has less oxygen molecules. This means that if you were there, you would need to take more breaths to get the same amount of oxygen as you would at lower altitudes. Higher elevation makes it even harder to breathe.

Which model for the initial settlement of the New World is NOT dependent on a cycle of glacial and interglacial periods
Answer:
Pacific Coastal Route
Explanation:
According to Coastal migration theory, Pacific Coastal Route is the route by which the people from northeastern Asia settle in America through water aided by boat.
This migration was believed to have been characterized by people migrating from one region to another through water travel supported by boat. Unlike the movement of people through the cycle of glacial and interglacial periods.
Hence, PACIFIC COASTAL ROUTE is the model for the initial settlement of the New World that is NOT dependent on a cycle of glacial and interglacial periods

Which of the following layers of the Earth is NOT one of the chemical layers?
Group of answer choices
A Core
B Crust
C Mesosphere
D Mantle
The (c) Mesosphere is not the chemical layer of the earth.
What is Mesosphere?
Mesosphere is a layer of the atmosphere.
The are 5 major layers of atmosphere are :-
• Troposphere:
We reside in this region, which is the lowest section of the atmosphere. It has the majority of our weather, including clouds, rain, and snow. The temperature in this region of the atmosphere drops by around 6.5°C every kilometer as one travels more above the planet. Depending on the weather, the actual temperature difference with height changes from day to day.
About 75% of the air in the atmosphere and virtually all the water vapour are found in the troposphere (which forms clouds and rain). The lowering pressure is the cause of the temperature drop with height.
• Stratosphere:
This rises to a height of around 50 km above the tropopause. The majority of the ozone in the atmosphere is found there. Because this ozone absorbs ultraviolet (UV) energy from the sun, the temperature rises with height. Over the summer pole and the winter pole, stratospheric temperatures are greatest and lowest, respectively.
The ozone in the stratosphere shields humans from skin cancer and other health problems by absorbing harmful UV rays.
• Mesosphere:
The mesosphere is the area located above the stratosphere. Mesosphere kills the majority of meteors and asteroids before they reach the earth's surface, the mesosphere serves as the planet's protective layer. It is the lowest and coldest part of the atmosphere. At the mesosphere when the temperature once again drops with height, it is roughly -90°C.
• Thermosphere:
Thermosphere is the layer above the mesosphere where temperatures rise with height. The sun's powerful ultraviolet and X-ray radiation is what causes this rise in temperature.
• Exosphere:
The exosphere is the area located above 500 kilometres. It mostly consists of oxygen and hydrogen atoms, but since there are so few of them, they don't often collide; instead, they move on "ballistic" trajectories as a result of gravity, and some of them even manage to escape into space.
What are the layers of the earth?The earth consists of three major parts. The three parts of the earth's structure are :- the core, the mantle, and the crust.
This earth's surface layer is mostly made up of the solid rocks granite and basalt. The two types of crust are oceanic and continental. Basalt makes up the bulk of the oceanic crust, which is denser and thinner.
Magma, a kind of semi-molten rock, makes up the mantle. The lower mantle, which is composed of a more solid rock and is hot enough to melt but remains solid owing to pressure pushing on it, may be divided into two distinct parts.
While the core is made up of metal—specifically, iron and nickel.

If a rock started with 1,000 atoms of a parent but now contains 250 atoms, how many half lives have passed?
a. 0.5 half lives.
b. 1 half life.
c. 2 half lives.
d. 0.25 half lives.
Answer:
Option C. 2 half lives.
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
Half-life is defined as the time taken for the substance to reduce to half its original side. Mathematically, it can be obtained as follow:
N = 1/2ⁿ × N₀
N is the amount remaining.
n is the number of half-lives.
N₀ is the original amount.
Using the above formula, we can obtain the number of half-lives as follow:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
N = 1/2ⁿ × N₀
250 = 1/2ⁿ × 1000
Cross multiply
250 × 2ⁿ = 1000
Divide both side by 250
2ⁿ = 1000/250
2ⁿ = 4
Express 4 in index form
2ⁿ = 2²
n = 2
Therefore, it will take two (2) half lives for the amount to get to 250 atoms.

Do you think migration was a voluntary move or involuntary? Why?
Answer:
People who flee persecution and violence in their own country are considered asylum seekers while the people who decide to move to another country in order to seek employment and better life opportunities are considered migrants. Migrants can be legal, moving threw documentation. Migrants are usually people with a strong resources in order to prepare their journey and arrival in the country of the destination. They save money, they gather the information about the trip and the destination and about the potential employment there, like how mast Europians or Asians come to america. They speak to friends and family at the destination who will help them upon arrival. They may speak to travel agents, potential employers at destination or middlemen of different sorts. They may try to learn the language of the destination country. In short, migrants clearly make decisions and take up the actions in order to prepare for their migration. This does not necessarily mean their migration is voluntary. The reasons for leaving their country of origin may have to do with circumstances that are beyond their the control. Migrating is not a decision taken easily, it involves high costs. They may do this to help family
It can be both
People either can be made to move involuntarily, or forced, or are put in situations that encourge relocation, or reluctant, or if they choose to migrate ,or voluntary.

Imagine, it is 50 years in the future and there are numerous seismic monitoring stations on Mars. A marsquake (earthquake, but on Mars) originates at Olympus Mons, the blue triangle on the map. Both S and P waves from the marsquake are detected everywhere there is a green on the map. But neither S nor P waves are detected where there are red x signs on the map. What does this tell the future scientists about Mars
Answer:
That the waves on mars can either sometimes be false Or they are too small to be tracked.

youcan't drinkwine. It's expensive.
This question is incomplete. Here's the complete question.
Make two sentences for each of the following using: (i) too, and (ii) not……. enough.
You can't drink wine every day. It's expensive
Answer:
You can’t drink wine every day. It’s expensive.
Wine is too expensive to drink every day.
Wine is not cheap enough to drink every day.
Explanation:
Not enough and too are used to describe something as inadequate.
If the amount of something is more than what we would like we can use the too + adjective form, which only applies in negative circumstances, such as the wine being too expensive. But we can also use the not + adjective + enough form to talk about something that hasn´t reached the desired level.

In case the question gets cut off: which world map below shows the locations of major plate boundaries where most earthquakes and volcanoes occur on earth?
Answer:
The map labeled with 1 shows the major plate boundaries and where most of the earthquakes and volcanoes occur.
Explanation:
The map labeled with number 1 is showing us the plate boundaries. This can easily be confirmed as the lines that are drawn are in the exact same places where the plate boundaries are located. The plate boundaries are the places that are tectonically the most active on Earth, with earhtquakes and volcanoes being a regular occurrence.
Not all plate boundaries though have around the same intensity of earthquakes or number of volcanoes. This is due to the difference in plate boundaries. At the convergent plate boundaries (depending is it between two continental, continental and oceanic, or two oceanic) there can be the formation of volcanoes or mountain ranges, with earthquake activity varying a lot. At transform boundaries, there isn't volcanic activity but there are a lot of earthquakes. At divergent boundaries, earthquakes are rare, but there is intense and constant volcanic activity.

What are three differences between brittle and plastic strain (may include both characteristics of the strain as well as the conditions and locations where each type of strain occurs), and give an example of the type of structure (deformation feature) associated with each type of strain. Make sure you clearly identify which type of strain is associated with each different trait and feature.
Answer:
elastic deformation: the rock returns to its original shape when the stress is removed.
plastic deformation: the rock does not return to its original shape when the stress is removed.
fracture: the rock breaks.
Explanation:
Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.
A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries.
Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries.
When forces are parallel but moving in opposite directions, the stress is called shear (figure 2). Shear stress is the most common stress at transform plate boundaries.
Stress In Earth’s Crust
Enormous slabs of lithosphere move unevenly over the planet’s spherical surface, resulting in earthquakes. This chapter deals with two types of geological activity that occur because of plate tectonics: mountain building and earthquakes. First, we will consider what can happen to rocks when they are exposed to stress.
