what if all the ice melted on earth? what are some concerns shared about rising sea levels?
Answer:
If all the polar ice and glaciers melted, there would be a notorious rise in sea level, leaving thousands of cities located in lowlands, such as Miami or New Orleans, totally submerged under water.
Due to the melting of land ice, more water ends up in the oceans; for example, all the ice in Greenland spread across the oceans would account for seven meters of water; and a theoretical situation where all the ice in Antarctica would melt would result in an elevation of 61 meters.

The most common misunderstanding about climate change is that the
Earth's climate has changed naturally in the past, therefore humans are
not the cause of global warming. That is not correct. What are some
analogies or rebuttals that help debunk this myth?
While yes, the earth has changed before, the reason it is changing now is because of greenhouse gases being pushed into the atmosphere by human activity. Also climate change take hundreds of thousands of years by slow process, this is the fastest the climate has ever changed. The last 20 years have had the 19 hottest years in recorded history.

Physical Weathering – Lewis Range, MT. In temperate climates, water can infiltrate cracks in the sedimentary rocks (and other types as well), and with repeated freeze-thaw cycles, can break the rocks apart by the physical weathering process of frost/ice wedging. The broken rocks often fall down the steep slope to form a pile of rubble at the base of the cliff. What is this pile of broken rocks called?
Answer:
Scree.
Explanation: A scree is a collection of broken fragments at the bottom of a cliff, volcanoe, crags or, valley shoulders. Hope this helps. :))
A scree is a collection of broken fragments at the bottom of a cliff, volcano, crags or, valley shoulders is this pile of broken rocks called.
What is Physical Weathering?Physical weathering, often known as mechanical weathering, is the process through which rocks, minerals, and soils decompose. The primary physical weathering process is abrasion.
The process that splits rocks without changing their chemical composition is known as physical weathering, often referred to as mechanical weathering. Physical weathering can be seen in the following situations: swiftly moving water.
Physical weathering is the process through which rocks break down into tiny fragments. Some of the mechanisms that could lead to this include exfoliation, freeze-thaw cycles, abrasion, root expansion, and wet-dry cycles.
Thus, A scree is a collection of broken fragments at the bottom of a cliff, volcano, crags.

how does the sun rise water but it can also drain water
Answer:
the sun evaporates the water and the water rises. clouds collect the water and when it becomes heavy, the water falls as rain. I don't know how the sun can drain water.

Why are rain forests so crucial to the earth's biodiversity? Discuss the effects on species and the environment. *
Answer: Based on tropical rainforests, we see why biodiversity is so crucial in maintaining an ecosystem. Since rainforests have huge ranges of plants, many insects or animals will have more diverse preys. The reason why tropical rainforests have such variety may be linked to the warm, wet weather throughout the year. If an ecosystem had organisms that were not diverse, but had one or two different species, a sudden change in the environment can have a greater effect in destroying the population.
Explanation: I got this in formation from: https://biodiversityphotoproject.weebly.com/importance-of-biodiversity.html#:~:text=Based%20on%20tropical%20rainforests%2C%20we,will%20have%20more%20diverse%20preys.&text=If%20more%20organisms%20diversify%2C%20it,life%20forms%20in%20the%20ecosystem.

The term greenhouse effect describes Group of answer choices the trapping of heat energy in the stratosphere by nitrogen efforts by the White House to support environmental legislation the trapping of heat energy in the troposphere by certain gaseous molecules the trapping of heat energy in the troposphere by nitrogen occupational diseases of florists
Answer:
the trapping of heat energy in the troposphere by certain gaseous molecules.
Explanation:
Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.
Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.
Hence, the term greenhouse effect describes the trapping of heat energy in the troposphere by certain gaseous molecules such as water vapor.
Additionally, troposphere is the lowest and most dense layer of the earth's atmosphere that causes a significant change in weather and charactized by temperature decrease.
Answer:
the trapping of heat energy in the troposphere by certain gaseous molecules. (Or Green House Effect).

Directions and Analysis
Task 1: Functions and Transformations
Transformations can be thought of as functions that take the points from one object (the pre-
image) to the corresponding points on another object (the image). In the unit, you saw
examples of how algebra can be used to rewrite the coordinates of points after they have
been transformed. You can also use function notation to rewrite the coordinates. For
example, these statements show several different ways you can use function notation for the
translation, T, of a point 6 units in the positive x-direction:
• T(x, y) = (x + 6, y)
T:(, y) = (x + 6, y)
• T<6, 0>(x, y) = (x + 6, y)
16. o(x, y) = (x + 6, 9)
.
a. Write functions for the following transformations using function notation. Choose a
different letter to represent each function. For example, you can use R to represent
rotations. Assume that a positive rotation occurs in the counterclockwise direction.
translation of a units to the right and b units up
reflection across the y-axis
reflection across the x-axis
rotation of 90 degrees counterclockwise about the origin, point o
rotation of 180 degrees counterclockwise about the origin, point o
rotation of 270 degrees counterclockwise about the origin, point o
Functions for the following transformations are to be written using function notation:
A translation of a units to the right and b units up is T< a, b>(x, y) = (x + a, y + b).
Here, a units is translated to the right and b units are translated up.
- Reflection across the y-axis is R(x, y) = (-x, y).The y-coordinates remain constant, but the x-coordinates are reflected.
- Rotation of 90 degrees counterclockwise about the origin is R(x, y) = (-y, x).The point (x, y) becomes (-y, x) after the rotation of 90 degrees counterclockwise about the origin.
- Reflection across the x-axis is R(x, y) = (x, -y).The x-coordinates remain constant, but the y-coordinates are reflected.
- Rotation of 180 degrees counterclockwise about the origin is R(x, y) = (-x, -y).The point (x, y) becomes (-x, -y) after the rotation of 180 degrees counterclockwise about the origin.
- Rotation of 270 degrees counterclockwise about the origin is R(x, y) = (y, -x).The point (x, y) becomes (y, -x) after the rotation of 270 degrees counterclockwise about the origin.

ESSAY. Give a solution on the situation usually happens in hotel.
Because of the Christmas holiday season, the hotel is completely booked for this coming weekend; sadly, the reservations department made a mistake and double booked; however, the guest is adamant that he made a reservation and will be staying at your hotel this coming weekend. What is your plan for dealing with this issue?
Answer:
Booking rooms in other neighboring hotels.
Explanation:
As a head of the hotel, this my responsibility to arrange rooms in another hotels in order to solve this issue because there is no other way to solve this problem. There must be a lot of empty rooms in other hotels so the people who made reservation must be fitted in these hotels. In this solution, the other hotels also made profit from this situation as well as the reputation of our hotel also be protected. So booking of rooms in the neighboring hotels is the only solution for this problem.

Answer:
∆PQR ~ ∆PTS
Explanation:
In diagram shows that ∆PQR and ∆PTS share a common vertex, <P.
Therefore, <P = <P
Also,
<Q = <T = 70°
Based on the third angle theorem,
<R = <S.
From the above, we can see that all three angles in ∆PQR are congruent to all the three corresponding angles in ∆PTS, therefore,
∆PQR ~ ∆PTS

f f(x) = 3x^2 + 1 and g(x) = 1 – x, what is the value of (g – f)(2)?
Answer: f(x) = 3x^2 + 1
g(x) = 1 - x
(f - g)(x) = 3x^2 + 1 - (1 - x) = 3x^2 + 1 - 1 + x = 3x^2 + x
(f - g)(2) = 3(2)^2 + 2 = 3(4) + 2 = 12 + 2 = 14.
