Answers
Answer:
3. water mass A is warm and saltier
4. water mass C is cold and less salty
5. water mas C is the densest
6. Water mass A is the least dense.
Explanation:
Before answering the questions, we will review some theoric about water masses and their distribution.
On the sea surface, density increases from the equator to the poles. In-depth, density increases from the surface to the bottom of the ocean. Density distribution in depth is controlled by temperature.Water masses that are denser tend to sink faster than less dense water masses. Less dense water places above the denser water. The difference in density generates convective streams. Denser colder, and heavier water descends, while less dense, warmer, and lighter water ascends.
Vertical water motion in the ocean between the surface and the bottom is inhibited by the density contrast between the inferior layer and the superior one. However, in the poles, there is hardly any temperature variation between the surface and the bottom.
Cold and dense water masses come from the polar regions at higher latitudes. Different water masses can be differentiated from the surface to the bottom in the middle of the ocean.
Central water massIt is in the central region of the ocean. It generates between the subtropical convergent zones. It might reach up to 1000 mt deep. This mass of water is the most saline one, and its temperature ranges from 8ºC to 25ºC. It is the most saline water because it is subjected to high evaporation.
Intermediate water mass: AntarcticIt is under the central water mass. It generates in the artic and antarctic convergent regions. The most extended one is the antarctic one, which is originated in the subantarctic superficial water. Its temperature ranges from 2ºC to 7ºC, and its salinity ranges from 34,1o/oo to 34,7o/oo.
Deep Arctic water massIt is produced by the mixture of the high salinity water from the Gulf stream and the superficial subarctic water. These masses are in the Atlantic ocean. Its temperature ranges from 3 to 4ºC, and its salinity media is 34,9o/oo.
Deep Antarctic water massThe densest water mass. Originated during the winter in the Antarctic region, but can be found up to 30ºN of latitude. Its temperature ranges from -1ºC to 0.5ºC, and its low salinity is approximately 34.7 o/oo. They are in the Pacific and Indic oceans.
In the exposed image, we can identify
the X ax → Latitude → 0º is the Equatorthe Y ax → DepthA) This is the most superficial one, and is well-placed from the equator to the subtropics. More or less 40º latitude north and south. This mass is probably the central mass, which is the most saline due to the high evaporation rate, and the warmest. It is almost 1000 mt deep.
Question: what are two likely characteristics of water mass A in the diagram above?
3a. warm or cold
3b. less or more salty
Water mass A is warm and saltier.
B) This mass is coming from the north pole. At high latitudes, there is little variation of temperature between the superficial region and the deep region. It is placed under mass A. It is colder than A, and less saline.
C) This is the densest mass, coming from the south pole. A little variation of temperature between the superficial region and the deep region. It reaches up to 25º north in latitude, approximately.
Question: What are two likely characteristics of water mass C in the diagram above?
4a. warm or cold
4b. less or more salty
Water mass C is cold and less salty.
Question: which water mass is most dense?
A, B, or C
Remember that density increases from the equator to the poles, and from the surface to the bottom. So, the densest mass is C.
Question: which water mass is least dense?
A, B, or C
The same reasoning as before. Mass A is the most superficial one and between the subtropics, making it the densest mass of water.

d) rocks
Explanation:
lithosphere is the crust or ground surface
hydrosphere is all the water bodies
atmosphere is involve the air
With respect to the earth as a system, the lithosphere is concerned with rocks.
Hence, the correct answer is option d.
The lithosphere is the rigid, outermost layer of the Earth, encompassing the crust and uppermost part of the mantle. It constitutes the solid Earth's outer shell and is broken into large and small tectonic plates that float on the semi-fluid asthenosphere beneath.
The lithosphere's thickness varies, ranging from about 5 to 100 kilometers. This layer is crucial to Earth's geology and plate tectonics, as it hosts various geological processes, including volcanic activity, earthquakes, and mountain-building. It plays a vital role in shaping the Earth's surface and influencing the distribution of landmasses and ocean basins.

Explanation:
The largest carbon dioxide emitter is China. The majority of greenhouse gas emissions are produced during the production of electricity and heat.
Of all the greenhouse gases, fluorinated gases have the greatest potential to cause global warming. The average global temperature rose 2.1 degrees Fahrenheit during the past century. Options (D), (B), (A), and (D) are thus correct in that order.
What is the greenhouse effect?The greenhouse effect is a phenomenon in which heat from a planet's host star passes through its atmosphere and warms the surface of the planet, but greenhouse gases in the atmosphere prevent part of the heat from going directly to space, making the world warmer.
Without greenhouse gases, Earth would be below freezing, but the planet's natural greenhouse effect prevents this from happening. Additionally, when greenhouse gas concentrations rise due to human activity, more heat is trapped and the Earth gradually gets warmer.
Hence, chronologically, Options (D), (B), (A), and (D) are correct.

In the diagram to the left ADE is an isosceles triangle. Segment EC bisects DCB.
A. Find the measures of DAE, ECB, and EBC
B. Explain how you were able to find the measures of these three angles
Answers
Answer:
m<DAE = 35°
m<ECB = 37°
m<EBC = 71°
Explanation:
✔️Find m<DAE
∆ADE is said to be an isosceles triangle, therefore, the base angles, <DAE and <AED are of equal measures.
Thus, m<ADE is given as 110°. Therefore,
m<DAE = ½(180 - m<ADE)
Substitute
m<DAE = ½(180 - 110)
m<DAE = ½(70)
m<DAE = 35°
✔️Find m<ECB:
We are told that segment EC bisects <DCB. This implies that <DCB is divided into two equal angles, which are <ECD and <ECB.
This means that:
m<ECD = m<ECB
Since m<ECD is given as 37°, therefore:
m<ECD = m<ECB = 37°
m<ECB = 37°
✔️Find m<EBC:
m<EBC = 180 - (m<CAB + m<ACB)
m<CAB = m<DAE = 35°
m<ACB = 2(m<ECD) = 2(37) = 74°
Plug in the values
m<EBC = 180 - (35 + 74)
m<EBC = 180 - 109
m<EBC = 71°
Overall, sedimentary rocks comprising most of the oceanic crust tend to be much older than plateaus of rocks found far away from volcanic activity in the center of continents.
A. True
B. False
Answers
Answer:
A. True
Explanation:
Oceanic crust, while older than plateaus of rocks found far away from volcanic activity, it is much thinner, denser, younger, and of different chemical composition than continental crust. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. On the other hand, plateaus of rocks are formed from volcanic activities and are of more recent occurrence than oceanic crust.
Why do some provinces and territories have a lot of natural resources and others have very little?
Answers
Answer:
The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.
Explanation:
Some provinces and territories have a lot of natural resources and others have very little because Many physical elements, such as land, temperature, and altitude, influence the distribution of natural resources.
Why is there a lack of natural resources?Natural resource depletion happens when resources are depleted faster than they are replaced. Natural resources are those that exist in the absence of human intervention and can be renewable or non-renewable.
Based on their geographic position and historical geologic processes, various areas have access to diverse renewable or nonrenewable natural resources such as freshwater, fossil fuels, rich soil, or timber.
Many physical elements, such as land, temperature, and altitude, influence the distribution of natural resources. Because these characteristics change from location to place on this planet, the distribution of resources is uneven.

Global changes and problems such as population growth, deforestation, air pollution, burning natural gas, coal and oil, pesticides, industrial gases, carbon dioxide, and emissions contribute to global warming which results in a disbalance in the natural ecosystem and an increase in temperature.
What is deforestation?Deforestation is referred to as the cutting down of trees in large numbers which reduced the quantity of plant vegetation in order to perform commercial activities with the objective to develop better infrastructure.
If the number of greenhouse gases in the atmosphere suddenly increased, more heat would be radiated toward the surface of Earth, causing a dramatic rise in temperature.
Global issues and adjustments like deforestation, air pollution, burning of fossil fuels like coal, oil, and gas, pesticides, industrial gases, and emissions all contribute to global warming, which disrupts the natural ecosystem and makes it harder for organisms to survive.

Find the midpoint of the segment with the following endpoints.
(10,6) and (4,9)
Answers
Answer:
The coordinates of the midpoint are [tex]M(x,y) = \left(7, \frac{15}{2} \right)[/tex], respectively.
Explanation:
Given two distinct points ([tex]A(x,y)[/tex], [tex]B(x,y)[/tex]), the midpoint of the segment ([tex]M(x,y)[/tex]) is determined by the following expression:
[tex]M(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)
If we know that [tex]A(x,y) = (10, 6)[/tex] and [tex]B(x,y) = (4,9)[/tex], then the coordinates of the midpoint are:
[tex]M(x,y) = \frac{1}{2}\cdot (10, 6) + \frac{1}{2}\cdot (4,9)[/tex]
[tex]M(x,y) = (5,3) + \left(2,\frac{9}{2} \right)[/tex]
[tex]M(x,y) = \left(7, \frac{15}{2} \right)[/tex]
The coordinates of the midpoint are [tex]M(x,y) = \left(7, \frac{15}{2} \right)[/tex], respectively.
