The formula for the slope of a straight line is the change in y divided by the change in x. Since the y axis is equal to mass, and the x axis is equal to volume, slope is equal to mass divided by volume. Therefore, the slope of a mass versus volume graph is equal to density.
Aggregate -unconsolidated pieces of rock (I.e sand and gravel)
The answer would be Petrified Remains. This because the fossilization processes needs some remains to form in , some way before they can cast it.
Answer:
Petroleum Jelly
Explanation:
Petroleum jelly is made from the non-renewable resource, Coal. Apples are made from trees, which can be replaced, maple syrup is made from trees, and cotton is made from a plant. Coal, cannot reproduce.
When building some infrastructure, in this case a railway, that is close to a mountain slope, it is necessary to cover the mountain slope with a wire mesh.
The biggest reason for that is the safety.
The steep mountain slopes can be very dangerous, because the rocks undergo the natural processes of weathering and erosion, which causes the rocks to break up and fall downwards. The railway can be locked in that way because there will be rocks on it, so the trains will not be able to pass further. But what is more concerning is that rocks may start falling directly on the train itself, or on the railway but when the train is passing through, and can cause a tragedy. The train may get pushed of the railway, or the rocks may knock it down or get through the windows, so lot of lives can be lost, as well as lot of damage will be done too.
