The specialization of each hemisphere for certain tasks is called cerebral dominance
The specialization of hemispheres, also known as lateralization of function, is a characteristic of the organization of the human brain. This specialization has a few exceptions, both hemispheres can process almost all types of information, although they do so in different ways.
The right hemisphere processes information by playing an important role in communication, it is visual and deals in images more than words., although a small minority of people show dominance in language. The left hemisphere leans on the reading, writing, and calculations side of processing information. Even though the brain is divided into different hemispheres it takes tasks together as one, especially if the workload capacity increases.

The Indus plain is the most developed physical region of Pakistan.explain how the relief and drainage of the Indus plain have made it possible to carry out a variety of economic activities in this region
Agriculture is the second-largest sector of the Pakistani economy, accounting for approximately 21 per cent of GDP
It is highly dependent upon the Indus River system as farmland is mainly irrigated by water from the Indus River and its tributaries.
The low cost of water from the country’s irrigation system contributes to the over-exploitation of water resources and makes it challenging to maintain.
Solutions that address the overuse of water will not be easy to carry out, suggesting they are unlikely to be implemented in the near-term.
Even though Pakistan has limited land suitable for farming, the agricultural sector is a major component of its economy. While Pakistan has an arid to semi-arid climate, it is not physically water-scarce. Its water problems are caused by inefficiencies, waste and mismanagement, all of which are especially present in the agricultural sector. The majority of farmland is irrigated through a canal system that has, historically, provided ample water. In recent years, however, the situation has changed. Pakistan is now facing increased pressure from dwindling water supplies. Supply-side solutions could provide a short-term solution, but long-term solutions necessitate a reduction in the amount of water lost through poorly maintained infrastructure and finding other ways to conserve water.

These dipping cross-bedded layers blow Wind into sand dunes in the desert.
What are sand dunes?
A dune is a wind-formed sand mound that typically forms near a beach or in a desert. Sand accumulates in dunes when the wind drives it into a protected region behind a barrier. Sand grains build up to form dunes.
Every dune has a slip face and a windward side. The side of a dune that is windward is where the wind is blowing and pushing debris upward. Simply put, a dunes slip face is the unwinding side. In general, a slip face is more level than a dune's windward side.
A dune field or dune belt is a grouping of dunes. An erg is a sizable dune field. Namibia's Skeleton Coast Erg measures 20 kilometres in width and 2 to 5 kilometres in length.

What is ocean current?
Understanding how heat energy transfers between Earth's water bodies, landmasses, and atmosphere depends on mass flows of water, or currents. Since the oceans retain 97 percent of the planet's water and cover 71 percent of its surface, they play a significant role in the storage and global transfer of thermal energy. This heat is carried by regional and global ocean currents, which have an impact on the stabilisation of global climate patterns, the cycling of gases, and the delivery of nutrients and larvae to marine ecosystems.
Ocean surface and deep waters below 300 metres are where ocean currents are found (984 feet). Both locally and globally, they can flow water horizontally and vertically. The wind, tides, Coriolis effect, sun, solar energy, and changes in water density all contribute to the ocean's complex current or circulation system. Ocean currents are also influenced by the terrain, shape, and surrounding landmasses of ocean basins.

The theory of uniformitarianism was developed by Charles Lyell in the 19th century and is based on the writings of James Hutton. According to Uniformitarianism, the forces and processes that can be seen at the surface of the earth are the same ones that have sculpted the planet's terrain throughout natural history.
Erosion, deposition, compaction, and uplift are the four processes that are mentioned above as sculpting the ground. These processes happen at incredibly slow rates even though they are constant. Hutton, a farmer, understood that erosion rates were so slow that it would take an impossibly long time to see significant changes in the Earth's landscape.
Furthermore, according to Uniformitarianism, these processes have continued throughout the course of nature. In 1his book Theory of the Earth, James Hutton states, "We find no evidence of a beginning - no hope of an end."

Anticlines, faults, salt domes are some oil traps
What is Anticlinal trap?
An area of the subsurface where the strata have been forced into producing a dome shape is known as an anticline. If such a dome-shaped layer of impermeable rock exists, hydrocarbons can build up at the crest until the anticline is filled to the spill point, which is the highest point from which they can escape. The hydrocarbon sector considers this kind of trap to be by far the most important. Look at a geological map or fly over the area to spot anticline traps, which are typically long oval land domes.
What is a Fault trap?
The shifting of impervious and permeable rock strata along a fault line created this trap. The impermeable rock now abuts the permeable rock of the reservoir, blocking further hydrocarbon migration.
In some circumstances, an impermeable material (like clay) may be smeared along the fault line, which also serves to inhibit migration. It's called a clay smear.
What is a sold dome trap?
Due to their increased buoyancy, masses of salt are driven up through clastic rocks, finally breaking through and rising towards the surface (see salt dome). This salt is impermeable, and when it passes through a layer of permeable rock through which hydrocarbons are migrating, it obstructs the channel in a manner similar to that of a fault trap. This is one of the factors contributing to the considerable interest in subsalt imaging, despite the numerous technological difficulties that come with it.

how do agricultural and industrial pollutants reach remote locations such as the arctic and antarctica?
The substances are transported to the Arctic in the atmosphere by ocean currents, and also by rivers and ice in the Arctic. These are the most important means of transport, but pollutants carried by animals which move between the polar areas may also have some significance.
How do ocean currents pollute remote locations?
Because ocean currents flow slowly, it may take decades for contaminants from heavily industrialised and populated places to reach the ocean. The ocean currents carry pollutants that are soluble in water and are dumped directly into the ocean or fall as rain into the ocean. The degree to which the contaminants are soluble in water will determine whether they bind to particles or sink to the seafloor. Such places might develop into what is known as sinks, or repositories for pollutants.
The layers in the water and the current systems govern the maritime transit of contaminants to the Arctic. It might take years for toxins to travel through the ocean and reach the Arctic. Then, they may stay under the water for a few years to several millennia.
Some radioactive compounds may be carried by ocean currents over great distances depending on how they behave in the marine environment.
Measures taken to stop pollutants from reaching the environment are delayed by the slow movement of the ocean currents towards the pole.
