What environmental impacts are caused by both surface mining and underground mining? Select the two correct answers.

A sinkhole formation after mining is complete

B local water contamination

C release of underground gases

D destruction of ecosystems

E destruction from overburden


I picked C and D, am I right? ​

Answers

Answer 1

Answer:

B. local water contamination

D. destruction of ecosystems

Explanation:

The mining, be it a surface one or underground one, has several negative impacts on the surrounding area. Two common negative impacts of both types of mining are contamination of the local waters, as well as the destruction of ecosystems.

The waters get heavily polluted with toxic chemicals pretty much always ad everywhere where there is mining. The main reason for this is that the nus-products from the mining are released into the waters. This causes high level pollution of the waters, thus making it not good for anything, and the aquatic life in the waters dies out rapidly.

The fact that the waters are heavily polluted means that everything that comes in touch with them becomes heavily polluted as well. Also, apart from releasing chemicals in the waters, the mining requires space, so the area is cleared out, and after that lot of toxic material is disposed on it. The majority of the plants can sustain that, so they die out, and since they are the basis of the ecosystems, the animals die out as well.

Sailors refer to the area where ships powered only by sails frequently get stuck as the (doldrums-trade winds-horse latitudes.) This area is at (90-0-60) degrees latitude.

Answers

Final answer:

The term 'doldrums' is used by sailors to refer to the area at 0 degrees latitude, where the wind often dies down, leaving sail-powered ships stranded.

Explanation:

Sailors refer to the area where ships powered only by sails frequently get stuck as the doldrums. This area is located at 0 degrees latitude, also known as the equator. The word 'doldrums' is used to describe a meteorological phenomenon called the Intertropical Convergence Zone (ITCZ) where the prevailing winds are calm. The doldrums is notorious for its calm periods where the wind disappears altogether, trapping sail powered ships for days or weeks.

Final answer:

The area where ships powered only by sails frequently get stuck is called the doldrums. This region is at 0 degrees latitude and is characterized by calm winds and little to no wind.

Explanation:

The area where ships powered only by sails frequently get stuck is called the doldrums. This area is at 0 degrees latitude. The doldrums are characterized by calm winds and little to no wind, making it difficult for ships to navigate. Sailors often try to avoid this region to ensure smooth sailing.

The doldrums, also known as the Intertropical Convergence Zone (ITCZ), are a region near the equator characterized by light, variable winds and often calm or stagnant conditions. It's marked by low pressure and convergence of trade winds. Sailors historically dreaded it due to the lack of reliable wind for sailing.

What have you learned about radioactive dating? Check all that apply. Unstable atoms release particles. The radioactive decay of an element occurs at a constant rate. A half-life is half of the lifetime of a radioactive element. At one half-life, half of the original unstable element has decayed. All elements are radioactive.

Answers

Answer:

(1.) Unstable atoms release particles.

(2.) The radioactive decay of an element occurs at a constant rate.

(4.) At one half-life, half of the original unstable element has decayed.

Explanation:

The other answer was incorrect and after putting those answers in, it corrected itself to A, B and D.

Based on the scientific findings and the available options, the following can be concluded in the radioactive dating:

Unstable atoms release particles: this is often referred to as radioisotopes. It is caused by the unevenness of protons and neutrons quantity in the atomic nucleus.

The radioactive decay of an element occurs at a constant rate: this is dependent on the quantity of the radioactive atom

At one half-life, half of the original unstable element has decayed.

Radioactive dating is a scientific method or process upon which natural minerals ' age such as rocks is measured.

The purpose of radioactive dating is to measure the age of natural resources through the radioactive isotope.

Hence, in this case, the correct answer is options A, B, and D.

The Coriolanus effect influences

Answers

Answer:

The Coriolis effect influences wind by deflecting its path to the right in the Northern Hemisphere. The sequence of weather satellite images shows that the actual wind direction is from the southwest. The satellite images show atmospheric motion over the northern Pacific Ocean for a 36-hour period.

Explanation:

The Coriolanus effect influences wind and ocean currents.

Explanation:

It is defined as an  effect that acts upon the objects and cause deflection as they travel long distances around Earth. It occurs due to the earth's rotation. As,earth spins in an counter-clockwise direction, therefore  anything large on its surface is to get deflected.

Thus,the Coriolis effect  not only influences the wind trajectory also changes the ocean currents and it also influences the weather condition.Due to this effect it also affect fast moving objects and to describe such deflections the term Coriolis effect is used.

what problems might you face when modeling the sun and the revolving planets to the same scale? what assumptions might you have to make in your model​

Answers

If someone is trying to make a model of the solar system, and the goal is to represent it as it is, scaled down of course, then there will be one very big problem. The problem would be exactly the scaling. The Sun is significantly larger than any of the planets in the solar system. While the planets like Jupiter and Saturn can be represented by suing the same scale as the one for the Sun, that would not be the case for the likes like Mars and Mercury. The reason for this is that Mercury for example, being the smallest of the planets in the solar system, has diameter that is just over 285 times smaller than that of the Sun. Considering that in order for the model to be practical, the Sun will be made to be very small, it will be almost impossible to represent Mercury as it will be incredibly hard to even notice it. This is why in practice, when the solar system is represented, the scale used for the Sun and for the planets is not the same, so that the planets can be seen properly, not be just very small dots.

Answer: Planets such as Mercury are so much smaller than the Sun that it would be difficult to draw them to the same scale. On the same piece of paper or computer screen, Mercury would appear as a mere dot if the Sun were included in the model.

Why are different elements used to date the fossil found in different rocks?

Answers

Answer:

The elements are used because the half lives can denote when it was trapped in the rock.

Explanation:

The half lives of different elements can help to determine when the fossil was created and without it, it would be much harder to determine the ages of fossils.

Answer:

Fossil is usually determined in two different ways; the methods include absolute and relative dating. Relative determines the approximate age through comparison with other related rocks and fossils with determinable age.

While absolute determines the age of fossils precisely using the radiometric dating in measuring isotopes decays. Ultimately the dating of fossils happens by relative techniques, and relative compares fossils with known age. Scientist uses different types of minerals to calculate the age of fossils if they have not been dated in the past generations.

Its due to the climate and location of the area.

Another example would be the Arctic....since it is the region farthest to the south it does not get much exposure to the Sun therefore it is much colder in the atmosphere.

It all pretty much depends on where it is in relation to the sun and how the atmosphere behaves in that region.
