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.

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).

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.

A. a unique assortment of behaviors and beliefs that distinguish a society.
B. a set of behaviors that allows one group to dominate another group.
C. a set of shared beliefs that only one racial group can have.
D. physical traits that pass from one generation to the next
Answer:
a unique assortment of behaviors and beliefs that distinguish a society.
Explanation:
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another.
A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication. Thus, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.
Hence, the statement which best defines the role of cultural traits to a group is that, it is a unique assortment of behaviors and beliefs that distinguish a society.
Basically, cultural traits play a significant role in the way of life of a group of people in that it is a unique collection of various cultural elements that are closely related such as behaviors and beliefs.

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.

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.

What do you know about the rock cycle and the three type of rocks?
Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material

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.

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.
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.
