what is activated carbon
The term "activated carbon," often referred to as "activated charcoal," refers to a kind of carbon that has undergone an oxygen-treatment process to create millions of minute holes between its carbon atoms.
Because of the huge surface area that is produced per unit volume during the activation process, activated carbon may adsorb (not absorb) a variety of inorganic and organic substances.
Several applications benefit greatly from activated carbon's exceptional adsorption properties, which can have a surface area per gram ranging from 500 to 1500 square meters.
Air and water filtration, as well as other industrial and medicinal uses, all frequently make use of activated carbon. Because of its large surface area, it is very effective in removing pollutants and contaminants from liquids and gases.

how does the water footprint vary for different types of countries?
The entire volume of freshwater utilised to generate goods and services consumed by individuals, communities, or countries is referred to as the water footprint and their consumption habits.
The water footprint of different countries varies according to their degree of development, the sorts of goods and services they produce.
Here are some general ways in which the water footprint of various countries can differ:
High-income countries: When compared to low-income countries, high-income countries have a bigger water footprint per capita. This is due to their increased use of commodities and services that require a large amount of water to produce, such as meat, dairy products, and industrial goods.
Agricultural countries: Because irrigated agriculture consumes a lot of water, countries that rely largely on agriculture have a greater water footprint. Egypt, Pakistan, and India are examples of such countries.
Industrialized countries: Due to the significant volume of water required in the manufacture of industrial goods such as steel, cement, and chemicals, industrialised countries have a bigger water footprint.

The difference between reserves and resources is ____________.
a. Resources exist where as reserves are only thought to exist
b. Reserves are the amount that can be mined today for a profit
c. Resources are the amount that can be minded today for a profit
d. None, they are the same
The correct answer is (b) Reserves are the amount that can be mined today for a profit, while resources are quantities of minerals or fossil fuels that are believed to exist in a given location, but are not yet proven to be economically viable to extract.
In other words, resources are potential sources of raw materials or energy that may be present in the earth's crust or other geological formations, while reserves are the quantities of those resources that are currently known to exist and can be extracted with existing technology and under current economic conditions.
The term "reserves" is typically used in the mining and oil and gas industries to refer to the estimated quantities of minerals or fossil fuels that can be extracted from a given deposit or field, while "resources" refers to the total estimated quantity of those materials that may be present in that location, regardless of their economic viability.

as a huge rotating cloud of particles in space gravitate together forming an increasingly dense ball, it shrinks in size and rotates slower. true or false.
The given statement "As a huge rotating cloud of particles in space gravitate together forming an increasingly dense ball, it shrinks in size and rotates slower." is true as due to the conservation of the angular momentum, the cloud rotates slowly and becomes smaller in size.
Conservation of angular momentum is basically a fundamental principle of physics according to which, in the absence of any kind of external torque, the total angular momentum of a particular system happens to remain constant.
Due to this conservation of angular momentum, as the cloud becomes smaller in size, it rotates slowly. As the cloud is getting contracted under the force of gravity, the particles keep getting closer to each other and this reduces the size of the cloud and it then rotates slowly.

which environmental condition leads to the formation of secondary pollutants?
Secondary pollutants are formed under conditions of intense sunshine. A secondary pollutant is created when other pollutants (primary) react with the atmosphere rather than being immediately released as such.
Pollutants known as secondary pollutants originate in the atmosphere. These pollutants are not released from a source in a direct manner (like vehicles or power plants). Instead, they are created when contaminants from these sources interact with airborne molecules to create new pollutants.
The air pollutants that are not immediately released are referred to as secondary pollutants. Ozone is a secondary air pollutant as a result. A colourless, intensely irritating gas called ground-level ozone is produced just above the earth's surface. Since it is created, it is referred to be a "secondary" pollutant.

The best definition of a river basin is: The area drained by a river and its tributaries.
A river basin is a geographic area that collects precipitation and channels it into a network of streams and rivers that eventually flow to the same outlet, such as a lake or an ocean.
It is bounded by high points or ridges called divides that separate one drainage basin from another.
River basins can range in size from a few square kilometers to millions of square kilometers.
The size of the river basin determines how much water flows through the river and how quickly it flows.

Plate movement is influenced by each of the following EXCEPT D. mantle plumes, which are a type of localized hot spot in the mantle that can cause volcanism and crustal deformation, but do not directly drive plate motion.
Plate movement is primarily driven by three main forces: slab pull, ridge push, and mantle convection. Slab pull occurs when a dense oceanic plate subducts beneath a less dense continental or oceanic plate, exerting a pull on the rest of the plate. Ridge push occurs when new oceanic crust is created at a mid-ocean ridge and the elevated rocks at the ridge axis push on rocks farther from the ridge. Mantle convection occurs when heat from the Earth's core drives convective flow in the mantle, which creates shear at the base of plates and can help to drive plate motion.

in what year are fossil fuel reserves expected to peak?
Option c) In 2030 year are fossil fuel reserves expected to peak. Fossil fuels have likely surpassed their peak level of use in the production of power and are set to start a phase of decline as the world's energy transition reaches a turning point.
The uncertainty surrounding the supply of fossil fuels has sparked research into other, stable energy sources to supplement fossil fuels as they become less abundant. However for at least the foreseeable future, the global energy market is anticipated to remain reliant on fossil fuels.
Oil and gas supplies are predicted to rise from 36 million barrels per day in 2006 to 46 million barrels per day in 2015, and then reach 61 million barrels per day by 2030, according to WEO 2007. Moreover, the 2006 estimates for oil and gas reserves are 1300 billion barrels and 6100 trillion cubic feet, respectively (BP, 2007b).
