Mantle material rises in convection currents because heated materials become less dense.
What is convection current?Convection is a single- or multiphase fluid movement that develops on its own as a result of the interaction between a fluid's body forces—most frequently gravity and density—and material property heterogeneity.Differential heating leads to convection currents. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. When a fluid's one component is heated, the difference in temperatures causes the fluid to flow in a particular direction. The process of a heated fluid rising and being replaced by a cooler one is known as convection cycle.Convection currents use the mass motion of a fluid, such as water, air, or molten rock, to move heat from one location to another. The earth's ocean currents, atmospheric weather, and geology are all controlled by convection currents' capacity to transport heat.Learn more about convection current here:

what is the use of coal in production of electricity according to Greenpeace
The use of coal in the production of electricity according to Greenpeace.
Coal still powers the world. About a third of the world's electricity is produced by coal. It's cheap and the quantity is large, but the price is reasonable. Combustion releases more carbon dioxide than oil and gas, so it's a big deal when it comes to climate change. Coal also produces toxic elements such as mercury and arsenic, as well as tiny particles of soot that cause air pollution. Despite climate commitments, many governments and countries still rely on coal. New coal-fired power plants are being built and new mines are being opened, which are also disruptive. Forests and other landscapes are destroyed, and mining waste pollutes rivers and fields. It may be cheap, but the real cost of coal is too high.
Greenpeace is an independent global campaign network. The network consists of 26 independent national/regional organizations in more than 55 countries in Europe, America, Africa, Asia and the Pacific, and Greenpeace International, a coordinating body based in Amsterdam, the Netherlands. Greenpeace researches, documents and identifies the causes of environmental degradation. We work to effect change through advocacy, consumer pressure, and public mobilization. And we will take peaceful direct action to protect the planet and promote solutions for a green and peaceful future.
For decades, Greenpeace and many other British politicians have promoted the world's leading offshore wind industry. Thousands of turbines now harness the strong sea breezes and the government recently pledged to bring offshore wind power to every home in the UK within his decade.

Which of the following is expected to increase due to change climate?
OA. Sea level
B. Freshwater
OC. Sea ice
O D. Land area
Sea level is expected to increase due to changes in the climate. Hence, option A is appropriate.
What is the meaning of Sea Level?The average surface level of one or more of the coastal bodies of water on Earth is known as the mean sea level, and it can be used to measure heights like elevation.
The basic level for determining height and depth on Earth is the sea level. The ocean's surface tends to seek the same level since it is one continuous body of water. The sea surface is not actually level due to winds, currents, river discharges, fluctuations in gravity, and temperature.
The average height of the ocean's surface is this. The addition of water from melting glaciers and ice sheets on land as well as the warming of the oceans are the two main contributors to the rise in the average global sea level.
Hence, option A is correct.

Direct and indirect ways in which the climate system can control the function of terrestrial ecosystems.
Climate alternate can alter where species stay, how they interact, and the timing of organic occasions, which can fundamentally remodel modern ecosystems and food webs. climate exchange can overwhelm the capability of ecosystems to mitigate extreme activities and disturbance, which includes wildfires, floods, and drought.
Weather trade exacerbates the hazard that non-native species (consisting of pests and pathogens) may also set up and unfold. We anticipate there to be local differences within the impact of climate change on biodiversity, reflecting exceptional species, weather, soils, and patterns of land use and control.
A terrestrial surrounding is a land-based total community of organisms and the interactions of biotic and abiotic components in a given place. Examples of terrestrial ecosystems consist of the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts.

“Weathering” refers to ___, while “erosion” refers to ___.
Weathering refers to the breakdown of rock into fragments at the Earth's surface. while erosion refers to the geological process by which soil material.
When the smaller rock pieces are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion. Weathering breaks the earth's surface into smaller pieces. This debris is displaced and deposited elsewhere in a process called erosion. Weathering can be caused by wind, water, ice, plants, gravity, and temperature changes.
Erosion and weathering are the processes by which rocks break down into fine particles. Erosion is the process by which rock particles are carried by wind and water. Weathering, on the other hand, breaks rocks apart without moving them. Erosion is the geological process by which soil material is eroded and transported by natural forces such as wind and water.
