in eutrophication, if excess nitrogen or phosphorus in a body of water causes the overgrowth of phytoplankton, how is it that this process will result in a reduction of oxygen in the impacted area?

Answers

Answer 1

When there is an overgrowth of phytoplankton due to excess nitrogen or phosphorus in a body of water, this process will result in a reduction of oxygen in the impacted area.

The reason for this is that the overgrowth of phytoplankton leads to an increase in the population of bacteria that decompose the dead plant matter, which consumes more oxygen in the water. This results in less oxygen being available for other aquatic organisms, leading to hypoxia and potentially causing harm to the ecosystem as a whole.

Eutrophication is the process of excess nutrients being added to a body of water, leading to an increase in the growth of phytoplankton and other aquatic plants. The excess nutrients can come from sources such as agricultural runoff, sewage, or fertilizers from residential lawns.

Comment on the potential of reforestation on effecting the local climate in Jordan.

Answers

Jordan is considered a country where deforestation, urbanization, overgrazing and other forms of land-use change have significantly affected the environment. This has resulted in the loss of important ecosystem services, the degradation of soil quality, and the depletion of natural resources.

However, reforestation has been identified as a potential solution to some of these environmental challenges. The effects of reforestation on local climate in Jordan can be seen in terms of the ability of forests to influence the hydrological cycle, provide shade, reduce temperature, and create microclimates that support different vegetation communities.

Describe characteristics of river in Bhutan

Answers

Bhutan is a beautiful region and among its most beautiful characteristics is its rivers. There are four major rivers in Bhutan, as well as a number of lesser streams around the country. The word for river in Bhutanese is : chhu and the largest river is dubbed the Drangme chhu. This river is of considerable importance to the economy and wildlife of Bhutan. It flows through the Royal Manas National Park and is a source for irrigation which is used by farmers throughout its valley and surrounding areas. It is also a source for drinking water in places along its route.

Drangme Chhu river of Bhutan is considered as holy river of the country which is spread over 376 km in Bhutan.

Where rivers of Bhutan drain?

Bhutan is a small country situated in the Himalayas, with four major rivers that cover 10% of the country's land and are regularly fed by Himalayan Glaciers. They eventually drain into the Brahmaputra River in India after running all the way across the country.

Bhutanese people hold rivers in high regard and associate them with a variety of religious beliefs. Every year, at least two persons are washed away in the waters of Mo Chhu, for example. As a result, many are reluctant to swim in it. It is considered bad luck to argue with them in any way.

what features in the the sedimentary or volcanic rock would you look for to tell u overturne limb

Answers

The following are the features in the sedimentary or volcanic rock that would be looked for to tell overturned limb:

1. Sedimentary rock

In sedimentary rocks, the upper surface is usually a layer of rock that has been eroded and exposed. This is commonly referred to as the "upper bed." The lower bed is located beneath the upper bed and is typically more resistant to erosion. The degree of weathering of the two beds can be used to determine whether or not a rock formation has been overturned.

2. Volcanic rock

In volcanic rocks, one can look for fractures and other structural features that may indicate that the rock has been overturned. Another method used to determine whether or not a volcanic rock has been overturned is to look for the presence of vesicles.

(a) an intrusive rock that cuts across other rock units (ex. 12.2 a) must be [ select ] than the units is cuts across.

Answers

(a) An intrusive rock that cuts across other rock units must be younger than the units it cuts across.

An intrusive rock refers to a type of igneous rock that forms when magma solidifies beneath the Earth's surface. When an intrusive rock cuts across other rock units, it provides important information about the relative ages of the rocks involved.

In geology, the principle of cross-cutting relationships states that a rock unit must be older than any rock that it cuts across. This principle applies to intrusive rocks as well. Therefore, if an intrusive rock is observed cutting across other rock units, it can be concluded that the intrusive rock is younger than the units it cuts across.

The reason for this is that the intrusion of the magma that formed the intrusive rock occurred after the formation of the rocks it cuts across. The magma, being younger than the surrounding rocks, was able to intrude and cut across them.

This principle is widely applied in the field of geology to determine the relative ages of rock formations and to reconstruct the geological history of an area.

In summary, an intrusive rock that cuts across other rock units is younger than the units it cuts across.

The amount of discharge at any given place and time that is solely the product of groundwater seepage is called

Answers

The amount of discharge at any given place and time that is solely the product of groundwater seepage is called base flow.

Base flow is a term used in hydrology to describe the volume of water that flows in a stream or river due to the slow and steady release of groundwater into the watercourse. This type of flow occurs when the water table is higher than the level of the streambed, allowing water to seep into the stream channel.

Base flow is an important component of the hydrologic cycle because it sustains stream and river flows during dry periods, when surface runoff is limited. It also plays a crucial role in maintaining water quality, as groundwater typically has lower levels of pollutants than surface water. Base flow can be affected by various factors, including geology, climate, land use, and water management practices.

For example, increased groundwater pumping can lower the water table and reduce base flow in streams and rivers, leading to ecological impacts.

Overall, base flow is a key indicator of groundwater availability and is an essential component of the water balance of rivers and streams. Understanding the dynamics of base flow is crucial for effective water management and sustainable use of water resources.

Answer:

Afghanistan's mountains have kept the country from ever being invaded.

Explanation:

Afghanistan is a country in terrible conditions, and this is not the case just nowadays but it has been like that for a very long time. Despite all of the internal troubles of the country and it seems to be very weak in pretty much every sector, it has never been invaded in the past few centuries, and very rarely in the more distant history and always it has been short-lasting.

The main reason for this has been the mountains and the general geography of the country. Very high and rugged mountains are separating the country from potential invaders. Even if an invading force manages to go through the mountains, it will suffer great losses just by doing so, and what comes next is desert and more rugged terrain, which will further damage them, so by the time they engage in battle, they will be too weak to conquer Afghanistan.
