Because of a limited freshwater supply, Dubai has to maintain a large-scale desalination process. How does the desalination process affect the environment? A. It causes aquifers to dry up. B. It causes air pollution. C. It makes oil spills more likely. D. It contributes to water salinity problems.
Answer: its b
Explanation:
Final answer:
The desalination process in Dubai primarily contributes to water salinity problems due to the discharge of highly saline wastewater, although it can also cause air pollution indirectly if the energy used is from fossil fuels.
Explanation:
The large-scale desalination process utilized in Dubai to address the limited freshwater supply has significant environmental impacts. The most pertinent one, in relation to the options provided, is that it contributes to water salinity problems. Desalination plants typically discharge highly saline wastewater back into the ocean, which can lead to an increase in the local seawater salinity, affecting marine ecosystems. The process itself is quite energy-intensive and can lead to air pollution, depending on the source of the energy used, but this is not typically considered the primary environmental effect. The options of causing aquifers to dry up or making oil spills more likely are not direct consequences of the desalination process.
Explain the difference between weather and climate.
Why is latitude a factor in the uneven heating of Earth's surface?
A particular air mass contains extremely cold, dry air. Based on this information, how would this air mass most likely be classified?
What's the intertropical convergence zone (ITCZ)?
How do polar jet streams differ from tropical jet streams?
Answer:
Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. ... Climate is the weather of a place averaged over a period of time, often 30 years.
As during the day earth heats from sun s short-range wavelength in night radiates out a long-wave from energy, as a result, the latitudes on the earth that are represented by the north and south line away from the equator experience uneven heating.
Air mass that have extremely cold and dry air is been classified as Arctic air mass. ... Equatorial air mass is warm and very moist and can be found in Equatorial region. Tropical air mass is warm and not humid and can be found in Mexico. Air mass plays an important role in controlling the weather significantly
Explanation:
Answer:
Weather refers to temporary atmospheric conditions that are occurring at a given point and time. Climate refers to the average weather conditions that occur in an area over an extended period.
Regions nearer the equator receive sunlight more directly than regions located farther from the equator. As a result, regions near the equator experience warm temperatures all year. Regions located farther from the equator experience more temperature fluctuations.
An air mass containing extremely cold, dry air would likely be classified as a continental arctic (cA) air mass.
The ITCZ is the point at which trade winds from the Northern Hemisphere converge with trade winds from the Southern Hemisphere. This area typically experiences calm weather.
Polar jet streams occur at higher latitudes. They separate the polar easterlies from the prevailing westerlies. Tropical jet streams occur at lower latitudes. They separate the trade winds from the prevailing westerlies.
If forester John walks 18 paces in a chain, and he walks 50 paces between point A and B, how many feet has forester john walked?
Answer:
183.5 ft
Explanation:
A chain is a unit of length and it has the length of 66 ft. To calculate the value of each pace .
we have to get the value of each pace by dividing the length of the chain by the pace.
Therefore,
each pace = length of chain/18
each pace = 66/18
each pace = 3.67 ft
The value of each pace = 3.67 ft
How many ft has john walked , that is from point A and B.
He walks 50 paces
Therefore,
each pace is 3.67 ft that means 50 paces will be
50 × 3.67 ft
183.5 ft

Surface winds typically blow at an angle to isobars on a weather map, while winds aloft move air in a direction nearly parallel to the isobars. Which of the following factors best explains why surface winds move differently than winds aloft?a) africtionb) humidityc) clear air turbulenced) the pressure-gradient force
Answer:
The correct answer is A. Friction
Explanation:
Surface winds typically blow at an angle to isobars on a weather map, while winds aloft move air in a direction nearly parallel to the isobars. FRICTION is the factor that best explains why surface winds move differently than winds aloft.
Friction is a force that holds back the movement of a sliding object. It is also the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
It is also the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Friction is the factor that best explains why surface winds move differently than winds aloft.
Explanation:The factor that best explains why surface winds move differently than winds aloft is friction. Friction between the wind and Earth's surface causes surface winds to slow down and change direction, resulting in an angle to isobars on a weather map. In contrast, winds aloft are not affected by surface friction and therefore move in a direction nearly parallel to the isobars.

As understood by modern geologists, the principle of uniformitarianism implies that ____________.
a. the Earth has always had the same basic appearance that it has today.
b. igneous, metamorphic, and sedimentary rocks are uniformly mixed throughout the crust.
c. physical processes observed today (such as erosion and volcanic eruptions) have been active in the past at approximately the same rates.
d. physical processes observed today (such as erosion and volcanic eruption) occurred much more rapidly in the past, quickly sculpting the Earth’s surface.
The correct answer is c. physical processes observed today (such as erosion and volcanic eruptions) have been active in the past at approximately the same rates.
This is because the principle of uniformitarianism, as understood by modern geologists, states that the same natural processes that operate in the present have been occurring throughout Earth's history at relatively consistent rates.
Option a, stating that the Earth has always had the same basic appearance that it has today, is incorrect because the Earth's appearance has changed significantly over geological time due to processes such as erosion, tectonic movements, and climate changes.
Option b, stating that igneous, metamorphic, and sedimentary rocks are uniformly mixed throughout the crust, is also incorrect as different types of rocks are distributed unevenly in the Earth's crust based on geological processes and history.
Option d, Uniformitarianism suggests that geological processes have occurred over vast periods of time at relatively constant rates. While major events like asteroid impacts or catastrophic volcanic eruptions have occurred in Earth's history, the overall shaping of the Earth's surface is believed to have taken place gradually through the same processes we observe today

Which agent of erosion causes the sandblasting of bedrock
Answer:
Wind
Explanation:
Wind is an agent of erosion which causes the sandblasting of bedrock. Sandblasting is a stream of sand projected by compressed air. It is a high velocity blast of air or steam carrying sand to etch glass or to clean stone or metal surfaces.
In response to rising atmospheric conditions, wind is caused by the movement of gas molecules in the Earth's atmosphere. The winds act like a pneumatic scouring agent and the top layer of fine soil is dislodged and transferred to undesirable places as a result.
Answer:
Wind
Explanation:
Which agent of erosion causes the sandblasting of bedrock
glaciers
wind
running water
wave action
Gravity, water, wind, and glacier are things that can erode material
Sandblasting is process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air and is the most common method used for surface preparation; they can occur naturally, usually as a result of particles blown by wind causing aeolian erosion, or artificially
The loss of energy between trophic levels… Is due to energy changing from one form into another Is an apparent violation of the second law of thermodynamics Depends on the rate of primary production Is caused by the inefficiency of photosynthesis None of the above
Answer:
The answer is none of the above.
Explanation: The loss of energy between trophic levels is due to the fact that organisms from one trophic level are consumed by organisms from the next level. Considering the production of meat
compared with arable farming, humans eat meat, they act as secondary consumers whereas the animals eat plants like grass but if humans eat plants materials like rice, they are primary consumers. By this, the food chain is shortened, causing loss of energy in the conversion from one trophic level to the next.
Kevin uses 32 ounces of dried apples and 18 ounces of dried cranberries to make a fruit snack. He plans to sell the snack in 1 2 -pound containers. How many containers will he fill? Will any fruit snack be left over? Kevin will fill containers. There left over.
Kevin will fill 6 containers with his fruit snack mixture, and there will be 2 ounces of the mixture left over after filling these containers.
Kevin uses 32 ounces of dried apples and 18 ounces of dried cranberries to make a fruit snack. He plans to sell the snack in 1/2-pound containers. A pound is equivalent to 16 ounces, so a 1/2-pound container would hold 8 ounces of fruit snack. To calculate how many containers Kevin will fill, we first find the total amount of fruit snack by adding the weight of the dried apples and cranberries:
32 ounces (apples) + 18 ounces (cranberries) = 50 ounces (total fruit snack)
Next, we divide the total amount of fruit snack by the container size to find the number of containers he can fill:
50 ounces \/ 8 ounces per container = 6.25 containers
Since Kevin cannot have a fraction of a container, he can fill 6 complete containers, and there will be a remainder. To find the leftover amount, we calculate:
50 ounces - (6 containers x 8 ounces) = 2 ounces left over
Therefore, Kevin will fill 6 containers, and there will be 2 ounces of fruit snack left over.

b) moons around the planet Jupiter
c) Pluto

His discovery of the moon creators and the solar storms and the moons spinning around the Jupiter which did not go around the earth.Who created the modern model of the solar system by discovering that the planets move in eclipse
Answer:
I do believe that it was Johannes Kepler
Explanation:
Answer:
Kepler derived the three laws of planetary motion which changed the model of the Solar System and the orbital path of planets.
Explanation
The historical models of the Solar System began during prehistoric periods and is updated to this day. The models of the Solar System throughout history were first represented in the early form of cave markings and drawings, calendars and astronomical symbols. Then books and written records then became the main source of information that expressed the way the people of the time thought of the Solar System.
New models of the Solar System are usually built on previous models, thus, the early models are kept track of by intellectuals in astronomy, an extended progress from trying to perfect the geocentric model to eventually using the heliocentric model of the Solar System. The uses of the Solar System model began as a time source to signify particular periods during the year and also a navigation source which is exploited by many leaders from the past.
Astronomers and great thinkers of the past were able to record observations and attempt to formulate a model that accurately interprets the recordings. This scientific method of deriving a model of the Solar System is what enabled progress towards more accurate models to have a better understanding of the Solar System that we are in..
In 1609, Johannes Kepler, using his teacher's (Tycho Brahe) accurate measurements, noticed the inconsistency of the geocentric model and confirmed the heliocentric model is a more accurate and consistent model. Kepler derived the three laws of planetary motion which changed the model of the Solar System and the orbital path of planets. The three laws of planetary motion are:
All planets orbit the Sun in elliptical orbits and not perfectly circular orbits.
The radius vector joining the planet and the Sun has an equal area in equal periods.
The square of the period of the planet (one revolution around the Sun) is proportional to the cube of the average distance from the Sun.
The third law explains the periods that occur during the year which relates the distance between the Earth and the Sun.
Galileo's discoveries
With the help of the telescope providing a closer look into the sky, Galileo Galilei proved the heliocentric model of the Solar System. Galileo observed the phases of Venus's appearance with the telescope and was able to confirm Kepler's first law of planetary motion and Copernicus's heliocentric model. Galileo claimed that the Solar System is not only made up of the Sun, the Moon and the planets but also comets. By observing movements around Jupiter, Galileo initially thought that these were the actions of stars. However, after a week of observing, he noticed changes in the patterns of motion in which he concluded that they are moons, four moons.
Newton's interpretation
After all these theories, people still did not know what made the planets orbit the Sun. Until the 16th century when Isaac Newton introduced The Law of Universal Gravitation. This theory claimed that between any two masses, there is an attractive force between them proportional to the inverse of the distance squared.

The side of the moon that faces the sun is always illuminated, but that side does not always face Earth. The different phases of the moon are caused by the moon's near 28-day _____.
The phases of the moon are caused by a lunar cycle, a nearly 28-day cycle that the moon takes to orbit the earth. The changing angle of the Sun's illumination on the Moon's surface as it orbits the earth is what results in the changing phases of the moon that we see from earth.
Explanation:The moon's phases that we observe from Earth are dictated by the Moon's near 28-day cycle called the lunar cycle. This cycle is the period it takes for the moon to orbit the Earth, also known as its period of revolution. Since the Moon's period of revolution is equal to its period of rotation, it always keeps the same face towards Earth. The changing angle of the Sun's illumination on the Moon because of this revolution gives us the changing Moon phases.
During the lunar cycle, we see different amounts of the Moon's illuminated side. For example, during the full moon phase, the side of the Moon facing the Earth is fully illuminated by the Sun and is thus completely visible. At new moon, the Moon is between the Earth and the Sun, and the side of the Moon facing the Earth is not visible to us because it is not illuminated by the Sun. The gradually increasing and decreasing illumination of the Moon as seen from Earth is what causes the difference in appearance of the Moon's phases.

The moon's gravity causes how many tides every 24 hours?
Answer:
Explanation:
Ok, all of this information has been gathered but all tides have been counted by 24 hours and 50 minutes!
Coastal areas experience two low tides and two high tides every lunar day (This is where the 24 hours and 50 minutes come into play!)The two tidal bulges caused by inertia and gravity will rotate around the Earth as the moons position changesInertia: A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
In each 24-hour cycle, the moon's gravity induces four tides on Earth: two high tides and two low tides. This is primarily due to the differential gravitational force of the moon, with additional, more complex influences from the Sun and Earth's geographical features. The Sun's alignment with Earth and the moon also affects tidal variations, leading to spring tides and neap tides.
Explanation:The moon's gravity causes four tides every 24 hours, specifically, two high tides and two low tides. The moon exerts a differential gravitational force on the Earth, causing the water in the oceans to flow into two tidal bulges on opposite sides of the Earth. As our planet rotates on its axis, different regions pass through these bulges, leading to the observed high and low tides. This is a simplified model, and actual tides can be more complex due to factors like the gravitational effects of the Sun and the shape of coastlines and ocean basins.
Additionally, the Sun's gravitational pull can impact tides, but its effect is less than the Moon's, even though the Sun's gravitational attraction on Earth is significantly more powerful. The reason is the greater distance of the Sun from Earth. When the Sun, Earth, and Moon are aligned, the tidal effect is amplified, creating spring tides with higher highs and lower lows. In contrast, when the Sun is at a 90-degree angle to the Earth-Moon alignment, we experience neap tides with less pronounced highs and lows.
