Oceans absorb carbon dioxide (CO2) from the atmosphere through physical, chemical, and biological processes. This movement of carbon between the air, seawater, marine organisms, and the deep ocean is an important part of the global carbon cycle. Understanding how oceans absorb carbon dioxide helps us explain why the ocean influences Earth’s climate and why increasing […]
Ocean acidification is the gradual decrease in the pH of seawater caused mainly by the ocean absorbing increasing amounts of carbon dioxide (CO2) from the atmosphere. The word “acidification” does not mean that the whole ocean has become an acid like vinegar. Seawater is still slightly alkaline, but its pH is moving towards the acidic […]
Sea level rise means that the average height of the ocean surface is increasing compared with the land. It is not caused by a single process. The two main causes are the expansion of seawater as it warms and the addition of water to the ocean when land-based ice melts. Changes in the amount of […]
Recently updated on October 28th, 2026 at 07:42 amA glacier is a large, long-lasting mass of moving ice formed from compacted snow. Glaciers grow when they gain more ice than they lose and shrink when ice loss is greater than ice gain. The phrase glacier retreat describes the movement of a glacier’s front, or terminus, […]
Recently updated on October 28th, 2026 at 07:42 amClimate change affect rainfall patterns by changing the temperature of the atmosphere, oceans, and land. A warmer atmosphere can hold more water vapour, while warmer oceans can increase evaporation. These changes influence where, when, and how much rain falls. Some places may receive heavier rainfall and more […]
Recently updated on October 28th, 2026 at 07:44 amAn urban heat island is a city or built-up area that is warmer than nearby rural surroundings. This temperature difference happens because cities contain many roads, roofs, buildings, and other surfaces that absorb and store solar energy. Cities also have fewer plants, less exposed soil, and more […]
Recently updated on October 28th, 2026 at 07:46 amA heat wave is a period of unusually hot weather that continues for several days or longer in a particular region.

Recently updated on October 28th, 2026 at 07:26 amDeforestation means the large-scale removal of trees and forests so that the land can be used for farming, roads, buildings, mining, or other activities. Forests do much more than provide wood. They influence temperature, humidity, rainfall, wind movement, soil moisture, and the storage of carbon. When a […]
Recently updated on October 28th, 2026 at 07:36 amLemon juice tastes sour because it contains acids, mainly citric acid. When citric acid dissolves in water, it releases hydrogen ions. These ions are responsible for many acidic properties, including sour taste, a low pH, and the ability to change the colour of some indicators. In this […]
