What happens when glaciers melt!
a. land bridges are covered with water
b. climate changes result in animal extinctions
C. glaciers melt and cause massive floods
d. all of the above
d. all of the above
When glaciers melt, all of the mentioned consequences can occur:
a. Land bridges being covered with water: Glacial meltwater can cause sea levels to rise, which can submerge land bridges and low-lying coastal areas.
b. Climate changes resulting in animal extinctions: The loss of glaciers can disrupt ecosystems and habitats of numerous animal species, leading to their decline and potential extinction. Glaciers also play a role in regulating temperature and moisture in certain regions, so their disappearance can affect regional climates.
c. Glaciers melting and causing massive floods: As glaciers melt, large amounts of water are released, contributing to the increase in water levels of rivers, lakes, and oceans. This can lead to flooding, especially in areas downstream from the glacial meltwater sources.
When glaciers melt, multiple changes occur. Let's go through each option and see which ones are correct:
a. Land bridges are covered with water: This statement is correct. As glaciers melt and their ice turns into water, the water level in oceans and other bodies of water rises. This can lead to the submergence of land bridges, which are narrow strips of land connecting two larger land masses.
b. Climate changes result in animal extinctions: This statement is also correct. Glacial melting can contribute to climate change, causing shifts in temperature, precipitation patterns, and overall ecological conditions. These changes can negatively impact various animal species and their habitats, potentially leading to extinctions.
c. Glaciers melt and cause massive floods: This statement is partially correct. While glacial melting can contribute to increased water supply and raise the risk of flooding, it is important to note that it is not the sole cause of massive floods. Other factors such as heavy rainfall or dam failures can also contribute to such events.
Therefore, the correct answer is d. all of the above, as all of the mentioned outcomes can happen when glaciers melt.
