Why are time zones necessary

Answers

Answer 1

Answer:

A time zone is a region of the Earth that has adopted the same standard time (local time).

-Most adjacent time zones are one hour apart (although a few are 30 minutes).

-They compute their local time as an offset from Greenwich mean time (GMT).

Explanation:

Answer 2

Answer:

As earth rotates, the different countries or different part of the earth are at daytime and nighttime. Since they have different daylight and nighttime times, we would need time zones.

Why is it that an aneroid barometer is able to measure altitude as well as atmospheric pressure? Why is it that an aneroid barometer is able to measure altitude as well as atmospheric pressure? Aneroid barometers use radar to measure altitude. Atmospheric pressure is independent of altitude. Atmospheric pressure increases as altitude increases. Atmospheric pressure decreases as altitude increases.

Answers

Answer:

Atmospheric pressure decreases as altitude increases.

Explanation:

The reason that an aneroid barometer is able to measure both the altitude and the atmospheric pressure is due to the face that the as air rise up its atmospheric pressure decrease. When measured form the means sea levels and on the ground, the surface the pressure is more thus the device can tell this difference. This instrument is essential for the weather analysis and matching the atmospheric pressure to the altitude. The average pressure on the earth's surface varies from 940 to 1040 Pascal. Thus the air becomes thinner as we move up the altitude.

The correct answer is D. Atmospheric pressure decreases as altitude increases. An aneroid barometer measures both atmospheric pressure and altitude because atmospheric pressure decreases with increasing altitude.

A barometer is a device that measures atmospheric pressure. There are different types of barometers, one being the aneroid barometer, which uses an evacuated flexible metal cell to measure pressure. When air pressure changes, the metal cell either expands or contracts, and this change is used to determine the atmospheric pressure.

An aneroid barometer can also measure altitude because atmospheric pressure decreases as altitude increases. This means that as you go to a higher altitude, the air pressure drops. By calibrating the barometer to display altitude instead of pressure units, it can effectively function as an altimeter. This principle relies on the known relationship between pressure and altitude, allowing the barometer to infer elevation from pressure readings.

The complete question is:

Why is it that an aneroid barometer is able to measure altitude as well as atmospheric pressure?

A. Aneroid barometers use radar to measure altitude.

B. Atmospheric pressure is independent of altitude.

C. Atmospheric pressure increases as altitude increases.

D. Atmospheric pressure decreases as altitude increases.

The Lost River is not really "lost." Suppose that a molecule of H2O falls as a raindrop into Lost River and eventually enters the Gulf of Mexico. Describe how this water molecule moves from one hydrologic reservoir to another as it travels from the rainstorm to the Gulf.

Answers

Answer:

The Colorado River (that is The lost river) proceeds from Rocky mountains into the Gulf of Calfornia. At the US & Mexico border, the Colorado river deflects into the farmland & orchards of different states of USA eldorado valley and other smaller basins.

After eight weeks of running through its delta, the fresh waters of the Colorado River meets the high tides of the briny sea.

Colorado’s nutrient-rich freshwater used to mixed with the Upper Gulf’s salty tides to create the perfect water chemistry and nursery grounds various water creatures of great commercial and cultural importance to the region, this was prior to the construction of big dams and diversions of the 20th century.

Cheers!

Final answer:

The water molecule moves from one hydrologic reservoir to another as it travels from the rainstorm to the Gulf of Mexico by following the water cycle.

Explanation:

The water molecule moves from one hydrologic reservoir to another as it travels from the rainstorm to the Gulf of Mexico by following the water cycle. First, it falls as rain during a rainstorm. The rainwater can then flow over the land surface as surface runoff or seep into the ground as groundwater. Eventually, it enters a river or stream and is carried downstream toward the ocean. Along the way, the water molecule can evaporate and become water vapor, which can then condense into clouds and fall as precipitation again. This cycle continues as the water molecule moves through different reservoirs until it ultimately reaches the Gulf of Mexico.

The course discussed the first component, ecological integrity, in the most detail, with references to social justice and economic prosperity. Provide, in your own words, how each component can work together, as well as the difficulties of maintaining each with the influences of the others.

2. In the freshwater marshes unit, there are several examples of humans now emulating nature. Provide one of them.

3. How can you, as an individual, change behavior or practice to be a more sustainable individual?

Answers

Answer:

Sustainability is the ability to meet the needs of  present population without compromising the needs of future generation. The three components are:

1. Environmental sustainability

2. Social sustainability and

3. Economic sustainability

Explanation:

1. In comparison, the three components are inter related as misuse of one component will lead to drastic result on another. Adequate environmental management can only be possible where the economic management is handled well to mitigate its effect on the environment, through enactment of sustainable laws that will help the growth in the economy of a nation without compromising the environmental well being of the nation.

In contrast, the three can hinder the growth of others through wrong use of natural resources for economic growth, without concern for the negative effects  they will have on the environment, while jettisoning those laws that have the ability to protect the environment and bring balance to the three components.

It is possible for the three components to work together to achieve equilibrium. This can be achieved where every component is considered in planning for the society.

Sustainable economic growth can be achieved when adequate and healthy laws are put in place in the management of the natural resources. Economic growth is derived by using the earth's resources for the good of the people. Bu that has tendency of putting undue pressure on the resources, thereby leading to their fast depletion. Therefore, enacting specific laws and guidelines in the orderly use and management of these resources will result in economic growth without harm to the environment.

However, there are difficulties most times in maintaining this equilibrium. This can come by way of greedy capitalists who can go any length to sabotage sound social justice to achieve economic prosperity at the detriment of the environment. Corrupt leaders, can team up with corrupt business men and exploit environment for economic progress.

2. A good example in fresh water marshes unit where humans are emulating the nature can be seen from lots of acts and conventions  to protect the environment. Such act like Fresh water Acts of 1972 which was enacted to protect the chemical, physical and biological integrity of nation's water, thereby reducing the pollution of water and its components.

3. As an individual i can contribute to sustainability of these three components by the followings:

a. Proper farm ethics and encourage 3 R's of waste management reuse, recycle and reduce. This will reduce to manageable level the burden on the resources of the earth.

b. Obey and support all the laws, conferences and conventions aimed at sustaining the environment

c. Avoid greedy and sharp business practices that will have negative effects on the immediate environment.

What kind of seafloor does Galveston have based on the

Answers

Seafloor of the Galveston is full of sand and sediment which is suspended in and around the bay.

Which is not a result of the low water level of the Danube River?

a
Fish are dying in record numbers
b
Unexploded WWII bombs have been exposed
c
Ships and barges have become stranded
d
Illegal immigrants are wading across the river

Answers

The correct answer to the question of which is not a result of the low water level of the Danube River is option d, as it pertains to illegal immigrants wading across the river, which is unrelated to environmental consequences like those listed in options a, b, and c.

Which is not a result of the low water level of the Danube River? The options a, b, and c are indeed consequences of low water levels, as they can lead to the exposure of previously submerged hazards such as unexploded WWII bombs, stranding of ships and barges, and the death of fish due to changed habitats and water conditions. Option d, illegal immigrants wading across the river, is not directly a result of low water levels because the primary concern with illegal immigration would be border enforcement and security rather than environmental factors like river water levels.

Low water levels in rivers can cause significant environmental degradation, which is often reflected in the form of reduced fish populations and uncovered hazards. Such conditions can severely impact both natural ecosystems and human activities such as navigation and fisheries. However, the wading of illegal immigrants across the river is less about environmental issues and more about border security and human migration patterns.

Part C - Karst Topography Recall from the introduction that karst topography exists because some minerals dissolve when they come into contact with rainwater. Minerals that contain calcium carbonate are especially susceptible to dissolving. Sinkholes and springs are common karst landforms that have the following characteristics: • Sinkholes can develop slowly where rainwater infiltrates te dissolving soil and rock, slowly lowering the ground surface of an area. In these instances, sinkholes are shallow with gently sloping sides • Sinkholes can also form rapidly and catastrophically when the cave ceiling collapses, resulting in deep sinkholes with steep walls • Rainwater in karst landscapes flows on the surface differently than other types of terrain. Streams are fewer and less developed in karst areas because water readily infiltrates the ground • Limestone dissolution is often not spatially uniform. In some circumstances, nonuniform dissolution can lead to the formation of lower karsts, which are large structures of rock that have dissolved at a much lower rate than the surrounding rock that has eroded away Which of the following is true about karst landscapes? Select the two that apply. View Available Hints) Sinkholes form from the same process as cave formations the dissolution of minerals Consider two regions (Region A and Region B) with the same type of environment (eg, climate) except Region A has karst topography Region A must also have more streams. A karst landscape is expected in the southwestern United States where conditions are dry Karst topography erodes at different rates, meaning that tall karst towers might form. Sinkholes that form abruptly tend to be shallow and have gone, not stop walls

Answers

Final answer:

Karst topography forms as a result of the dissolution and erosion of soluble rocks, such as limestone. This often results in sinkholes and caves. The landscape varies as the rate of erosion and dissolution can differ across the area.

Explanation:

The options about karst landscapes that are true are: 'Sinkholes form from the same process as cave formations: the dissolution of minerals' and 'Karst topography erodes at different rates, meaning that tall karst towers might form.'

Karst topography emerges due to the erosion and dissolution of soluble rocks such as limestone. The process of dissolution often leads to the formation of sinkholes and caves, leading to a unique landscape. Different rates of erosion could result in the formation of tall karst towers.

It's also worth noting that the presence of a karst landscape does not necessarily mean that there are more streams in that area. Water in karst areas often infiltrates the ground, leading to fewer and less developed surface streams.

The climate region labeled with the number 1 on the map above is the __________ region

Answers

The climate region labeled with the number 1 on the map above is the ARID region

Explanation:

A region is arid when it is characterized by a severe lack of available water, to the extent of hindering or preventing the growth and development of plant and animal life.Arid regions by definition receive little precipitation—less than 10 inches (25 centimeters) of rain per year. Semi-arid regions receive 10 to 20 inches (25 to 50 centimeters) of rain per year. Most of the world's arid climates lie just north and south of the tropical rain forests of the equator. Mountain plateaus are another location where you might find an arid climate. The southwestern corner of the United States, for example, is quite dry and hot.Cold currents carry dry air, so these lands are blasted with dry air most of the year, which causes the low precipitation.Environments subject to arid climates tend to lack vegetation and are called xeric or desertic.

How many of the products or foods you use daily come from Asia’s many resources, industries, and ecosystems? Give examples of one or two Asian products or resources that are part of your daily life.

Answers

Answer:

Many of the products I use are from Asia's resources, especially food.

TWO EXAMPLES: rice (comes from Thailand) and fish sauce (aka "nouc mam") that comes from Vietnam.

The utilization of Asia’s natural resources has depended, to a large extent, not only on the development of technology but also on political circumstances. Thus, until the end of World War II and the beginning of the process of decolonization in Asia, most Asian countries were not free to develop their own natural resources independently and without reference to the economic interest of a colonial power. Cultural attitudes also have affected the utilization of resources. In India cultural taboos prohibit the slaughter of cattle either for food or to conserve resources when the animals are no longer productive.

Answer:

Asia is an enormous continent with a great variety of societies, cultures and ecosystems. Because of this, Asia produces an enormous variety of goods that are enjoyed all over the world. It is very likely that you use some of these products in your everyday life.

For example, many electronic, automobile and technological companies are based in Asia. If you own any products from brands such as Toyota, Suzuki, Nissan, Mitsubishi, LG, Samsung and Sony, you own a product from an Asian company.
