Bangladesh is a country of rivers and floods but groundwater is still a vital resource because it provides bacterially safe water and helps produce food for millions of people. In rural and urban areas almost the entire population rely on groundwater for potable water. In the early 1990s some 97% of the population used it for drinking, but this has now come down to about 80% due to the detection of arsenic in shallow groundwater. Use of groundwater in irrigation is increasing every year, and now more than 74% of the irrigated area is covered with groundwater. The country's industries also rely on groundwater for most of their water needs. Though Bangladesh has abundant rain and surface waters, these sources are not available when water demand is the most. Therefore, groundwater can be considered as the country's most important natural resource for ensuring public health and food security. Consider the options for groundwater contamination in Bangladesh and give recommendations for prevention and conservation of groundwater in Bangladesh.

The moon orbits earth about every 27 days. If you travel around the world in a day or two, what would you notice about the pattern of the moon phases?

Answers

Answer:

The Moon's phases repeat every 29.5 days, but it's orbit around the Earth only takes 27.

Explanation:

Why? In that time, as our Moon moves around Earth, the Earth also moves around the Sun. Our Moon must travel a little farther in its path to make up for the added distance and complete its phase cycle.

The moon orbit earth about every 27 days. So, there are different phases of the moon in a month. It is impossible to travel around the world in a day or two, but we can see different phases of the moon from different areas.

What is the moon?

The moon is the natural satellite of the planets. Earth has only one moon, other planets have a different number of moons. The moon revolves around the earth.

As the moon revolves around the earth, its different shapes are visible from different sides. The shapes are a Cresent moon, round moon, or no moon.

Therefore, each lunar orbit takes around 27 days. Therefore, there are various moon phases during a month. While it is not possible to cross the globe in a day or two, we may observe the moon's various phases from various locations.

Explanation:

A tree belt consists of a line where several trees are planted in a row, forming something like a fence. Like the fence, the plant belt aims to promote protection for an area that, for some reason, is fragile, like a dry and desertified land.

The best way to protect dry and desertified regions is with a vegetation cover, which can be done through the belt of trees.

What is the meaning of Suburban?

A suburban is a predominantly residential area located inside a metropolitan area, while it may also contain some commercial and mixed-use areas. A suburban may be a smaller city or metropolitan region, or it may be a distinct political entity.

A smaller hamlet is next to or within driving distance of a city. An outlying area of a city or town. The residential region just on the outskirts of a metropolis or major town is referred to as a "suburban."

A city or town's urban community is one where many people reside and where many different types of structures are clustered together. A suburban is an area where residents reside close to a city or town.

Due to the high number of suburbanites who travel to the city for work, suburbans are frequently referred to it as bedroom communities. Subdivisions with solely residential zoning are where the majority of suburban homes are found.

Hence, option B is correct.
