<span>The chemical elements</span><span> can be broadly divided into </span>metals<span>, </span>metalloids<span> and </span>nonmetals<span> according to their shared </span>physical<span> and </span>chemical properties<span>. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form </span>alloys<span> with other metals; and have at least one </span>basic oxide<span>. Metalloids are metallic-looking brittle solids that are either </span>semiconductors<span> or exist in semiconducting forms, and have </span>amphoteric<span> or weakly </span>acidic oxides<span>. Typical nonmetals have a dull, coloured or colourless appearance; are </span>brittle<span> when solid; are poor conductors of heat and electricity; and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise extraordinary.</span>
Answer:
I think it is D. A forest fire
Answer:
Carbon dioxide has been released by the burning of fossil fuels. This process is increasing the ocean's water temperature resulting in the glacier melting
Explanation:
The carbon dioxide emissions have constantly been on the rise ever since the Industrial Revolution occurred. The burning of the fossil fuels is the main reason why there is such high quantity of this gas released into the atmosphere. The carbon dioxide is a greenhouse gas, thus it contributes to the arming up of the atmosphere. Because the atmosphere is warming up, the water is warming up as well. The higher temperature of the water results in melting of the glaciers, such as Thwaites Glacier. As the process continues, more and more of the glacier will be melted, with the end result being relatively big rise of the sea level.
