Explain different methods used to prevent salinity?
Explanation:
Type of salinity and their prevention
There are different types of salinity, each with different causes and varying treatment.
Dryland salinity is the accumulation of salts in the soil surface and groundwater in non-irrigated areas. It is usually the result of three broad processes:
groundwater recharge (or deep drainage)
groundwater movement
groundwater discharge.
Often it results from replacing deep-rooted native vegetation with shallower-rooted crops and pastures, which take up less water. Unused rainwater leaks into the ground causing groundwater to rise and dissolve salts stored deep in the soil. The salty water may:
rise to the surface causing waterlogging and/or scalding
emerge at the break of a slope as seeps
flow over the surface or underground into streams and rivers.
Irrigation salinity
Irrigation salinity is the rise in saline groundwater and the build-up of salt in the soil surface in irrigated areas. It is caused by using large volumes of irrigation water that locally raise groundwater levels and mobilise salt. Irrigation salinity is made worse when water used to irrigate is from salty sources.
Irrigation salinity can be controlled by using water efficiently. Crops should receive only the amount of water they can actually use. Reducing water usage in irrigated areas generally requires changes to irrigation infrastructure and technology, and better matching of crops to soil types.
Urban salinity
Urban salinity is a combination of dryland and irrigation salinity processes and is mainly caused by rising groundwater bringing salts to the land surface. The rise in groundwater is caused by blocked or changed natural drainage paths due to:
urban development
over-watering of parks and gardens
leaking pipes, drains and tanks.
In the urban environment, other sources of salt that can contribute to urban salinity include:
effluent
building materials
industrial waste water
fertilisers and chemicals.
Industrial salinity
Many industrial processes have the potential to increase salinity levels in rivers. Examples are:
saline water from mines (working and abandoned) from groundwater seepage and from rainwater coming into contact with mine workings or spoil
discharged cooling water from coal-fired power stations that has been partly evaporated, concentrating the salt content
effluent being discharged.
which prevailing wind blows through zambia in the rainy season
Answer:
Winds are predominantly easterly-southeasterly, although in the rainy season winds blow from the northwest and north. Wind speeds are rarely strong enough to cause damage. Although the major contrast is between the rainy season and the drier months, three seasons may be identified.

Using complete sentences, explain how innovations in transportation have impacted agriculture dramatically.
Answer:
See explanation
Explanation:
Innovations in transportation have impacted agriculture in many different ways. First of all, the innovation of faster means of transportation such as aeroplane have made it possible for agricultural produce to be moved across many miles without loosing perishable goods.
It takes a few hours to travel to areas which are very far apart using an aeroplane. Such a journey may take several days on a horseback.
Innovations in transportation have created new routes and opened new markets for agricultural produce. Areas that where hitherto inaccessible are now readily accessible and the markets in those places are now harnessed for the sale of agricultural produce.

The foreign minister of Zeria announced today that her country was severing diplomatic relations with Nandalo because of Nandalo's flagrant violations of human rights. But Zeria continues to maintain diplomatic relations with many countries that the minister knows to have far worse human-rights records than Nandalo does. Therefore, despite the foreign minister's claim, this latest diplomatic move cannot be explained exclusively by Zeria's commitment to upholding human rights.
Which one of the following, if true, provides the most support for the argument in the passage?
A) The country that currently buys most of Zeria's exports recently suggested that it might severely restrict its imports from Zeria unless Zeria broke off diplomatic relations with Nandalo.
B) Two weeks after the Zerian minister's announcement, several other countries cited human-rights violations as a reason for severing diplomatic relations with Nandalo.
C) More countries have expressed concern over reported human-rights violations in Nandalo than have expressed concern over human-rights violations in Zeria.
D) Nandalo has considered accusing Zeria of violating the human rights of Nandalo citizens living in Zeria.
E) The opposition party in Zeia has long advocated severing trade relations with countries that systematically violate human rights but has opposed severing diplomatic relations.
Answer: A) The country that currently buys most of Zeria's exports recently suggested that it might severely restrict its imports from Zeria unless Zeria broke off diplomatic relations with Nandalo.
Explanation:
When countries a lot of the times, there is usually an ulterior motive to it and this often comes down to money. In this case, keeping relations with Nandalo must have somehow threatened the money supply to Zeria and so Zeria had to take action against this.
Option A provides a plausible reason as to why this could be the case. If a country that buys a lot of Zeria's exports threatens to stop buying from Zeria, they would be inclined to act in a way that the country wants in order for the country to keep buying those exports and if that includes breaking off relations with Nandalo then it will be done.

What do u mean by natural vegetation ?
Answer:
Natural vegetation refers to a plant community, which has grown naturally without human aid and has been left undisturbed by humans for a long time. This is termed as a virgin vegetation. Thus, cultivated crops and fruits, orchards form part of vegetation but not natural vegetation.
For Example:
The grasses, shurbs and trees that grow on their own without any human interference or help are termed natural vegetation.
what is the role of gravity in maintaining the atmospheric layer around Earth?
Answer: It absorbs harmful ultraviolet radiation from the sun, helps keep Earth's surface warm via the greenhouse effect, and reduces temperature extremes between day and night. ... So, thanks to gravity, although some of Earth's atmosphere is escaping to space, most is staying here.
Explanation:
Hope it helps
Answer:
Earth's gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.

Which of the following best describes what would have to change to
transform a direct democracy into a parliamentary democracy?
A. An individual would have to take direct control of the government.
B. Executive leaders would have to be chosen from the legislative
branch.
C. An elite group would have to take control of the government.
D. An assembly of all citizens would have to take control from an
elected group
Answer: B. Executive leaders would have to be chosen from the legislative branch.
Explanation:
A parliamentary democracy is one where the executive government is controlled by the party that has the largest representation in the nation's legislative branch, the Parliament.
To be a parliamentary democracy therefore, an executive leader would have to be chosen from the legislature by the members of the party in the majority. This ensures that the legislature and the executive work closer together. Countries like Britain and Israel are parliamentary democracies.
