Scientists have discovered that as the glaciers melt in Greenland, the land is rising. This phenomenon is called rebound. Rebound occurs when a heavy load, such as a glacier, is removed from part of Earth's crust. Relieved of the load, the crust bounces back, like a spring Marco was looking at this picture of two boats sitting differently in the water. He decided to compare the way the two boats sít in the water to the way land is behaving in Greenland.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

c- cold periods in earth's history during which glaciers covered much of the surface.
