Answer:
a jet stream that brings alternating warm and cold periods
Explanation:
Jet streams are known as a composition of powerful wind that normally moves from west to east all over the world.
According to various research, it is considered strongest in winter, specifically showing a strong effect on weather in North America.
A jet stream at a normal pace is associated with normal cold and occasional warms, but at a strong pace, it usually creates heavy cold moving and warmth from north to south and vice versa. This is known as Rossby waves.
Hence, in North America, a winter weather change that might be associated with large amplitude Rossby waves is " a jet stream that brings alternating warm and cold period"
Summer and Winter are reversed in time between the Southern and Northern Hemispheres. (2 points)
True
False
Answer:
True
Explanation:
The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere. This means that in Argentina and Australia, winter begins in June. The winter solstice in the Southern Hemisphere is June 20 or 21, while the summer solstice, the longest day of the year, is December 21 or 22.

Adding a small amount of water to a substance increase its cohesion; whereas, adding a lot of water decreases its cohesion. Why?
a. A small amount of water will precipitate cement into the pores of the material, whereas too much water will not allow that coment to form.
b. A small amount of water increases surface tension and holds the grain together Too much water between the grains wil eliminate suface fordion.
c. Water has a small electrostatic force that disrupts the gravitational attraction of the grans and forces them to move away from each other.
d. A small amount of water decreases surface tension, allowing the grains to bond together, whereas too much water will increase surface tension and force the grains away from each other.
Answer:
b. A small amount of water increases surface tension and holds the grain together Too much water between the grains wil eliminate suface fordion.
Explanation:
The increase in cohesion between substances with the addition of a small amount of water is directly related to the increase in surface tension that water causes in this substance. However, with the exaggerated addition of water, superficial lust will not be able to be formed efficiently, or in any way, and therefore cohesion will be difficult.

Answer:
a
Explanation:
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.
The Earth is heated by light from the Moon.
True
False
Answer:
The moon is not very reflective so the earth only receives a very small amount of "light" reflected that was incident on the moon. Some of this reflected light may be infra-red (heat), but even if it is not some of the visible light reflected will be absorbed by the what it lights up on the earth.
Explanation:
false

A segment has midpoint at (2,-4) and an endpoint at (5,-9). What are the coordinates of the other endpoint?
Answer:
The coordinates of the other endpoint are (-1,1).
Explanation:
Mid point = (2,-4)
One endpoint = (5,-9)
We need to find the coordinates of the other mid points. Let it is (x₂,y₂). Using the mid point formula to find it.
[tex]\text{Mid-points}(x_m,y_m)=(\dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2})[/tex]
We have, [tex]x_m=2, y_m=-4, x_1=5, y_1=-9[/tex]
[tex]\text{Mid-points}(2,-4)=(\dfrac{5+x_2}{2}, \dfrac{(-9)+y_2}{2})\\\\\dfrac{5+x_2}{2}=2\ \text{and}\ \dfrac{y_2-9}{2}=-4\\\\5+x_2=4\ \text{and}\ y_2-9=-8\\\\x_2=-1\ \text{and}\ y_2=1[/tex]
So, the coordinates of the other endpoint are (-1,1).

Explain how plate tectonics and/or process of weathering, erosion, and deposition have shaped peninsula
Answer:
The material moved by erosion is sediment. Deposition occurs when the agents, usually wind or water, of erosion lay down sediment. Deposition changes the shape of the land. Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.

g) make two sentences for each of the following using
too and using not... enough
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.

PLEASE I HAVE A DAY ILL GIVE U BRAINLIEST AND GIVE A FREE QUESTION it's your turn to investigate the human impacts around the world grab your virtual lab coat and put your environmental science that you'll be taking a trip around the globe to explore 3 I ate your location you want investigate the cause and effect relationship of deforestation to server caitian organization you will also gather evidence of how these factors have impacted the environment over time (In this lab you will explore the impact that humans have on earth pleaseeeeeeee it mwan so much if you do ❤
Answer:
Deforestation main cause is from Humans correct. It's the process of permanent removal of trees to make room for something besides forest. This can involve clearing the land for agriculture or grazing, or using the timber for fuel, constructions. Forests cover more than 30% of the Earth's land surface. They've impacted by trees releasing carbon dioxide and other greenhouse gases. Forest loss and damage is the cause of around 10% of global warming.
Answer:
So, desertification means that something is larger or growing to destroy something and urbanization means the process of making an area more urban .So these two words mean almost the same, so it will impact the environment, because if something, coming or growing to destroy the environment, such as the Sahara dessert, it will affect the environment.
