The two minerals that are found in cement are : Silica and calcite.
<u>Explanation:</u>
Different minerals form the composition of cement but the minerals that are most commonly found in cement are calcite which is contained in the limestone.
The other mineral that is used in the production of cement is silica in the form of raw rock type used to make cement which is found in clay. So they form an important part of formation of cement.
The statement is correct.
The contour lines are a very good indicator of the relief. The closer they are to one another, the steeper the relief, and vice verse, the more distant they are from one another, the flatter the relief is.
In general, contour lines that are very close to each other can be noticed on the mountains, as most of the mountains have steep parts, or rather steeper slopes.
The more distant contour lines, on the other hand, can be found on places like the valleys or the plateaus, places that in general are much flatter.
