Answer: These processes in the tectonic plates in the crust, wind and water erosion, and deposition shape features on Earth's surface.
Explanation:
The tundra is a biome on the Earth that covers approximately 20% of its land mass, and it is almost exclusively located in the Northern Hemisphere. It is an environment that helps in the regulation of the CO2 in the atmosphere, and it is one of the biggest natural CO2 sinks. The living organisms in the tundra, are using the CO2 for their needs, thus removing parts of it from the atmosphere, and when they die, because the tundra is cold, and the decomposition is very slow, most of the CO2 remains trapped, and doesn't go into the atmosphere.
Unfortunately, the global warming is slowly changing the tundra, and prolongs the summer periods, thus reducing the permafrost period of the year, so the decomposition of the living organisms is getting quicker, and also bigger percentage of the CO2 from them gets to the atmosphere.
The world’s ocean is crucial to heating the planet. While land areas and the atmosphere absorb some sunlight, the majority of the sun’s radiation is absorbed by the ocean. Particularly in the tropical waters around the equator, the ocean acts a as massive, heat-retaining solar panel. Earth’s atmosphere also plays a part in this process, helping to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds, often vast distances. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area. Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides (the gravitational effects of the sun and moon). Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines. Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.
Snow and ice cover less of the Earth's surface as a result of melting due to an increase in global temperature, which also lowers albedo. More energy is absorbed due to the decrease in albedo, which leads to increased warmth and melting.
Global temperature is significantly influenced by the equilibrium between the amount of solar energy reflected and absorbed by the Earth's surface. Snow, ice, and water on Earth have different capacities to reflect and absorb solar energy, and melting polar ice triggers a positive feedback loop that hastens global warming.
Pollution, including soot, decreases the albedo of ice and speeds up melting.
