What land form is shaped like a triangle?
A Rock
What is the purpose of using angles when building a bridge?
They are used to support other elements of the structure as well as to divert the load to support columns which are usually based in the bed rock.
If a 7 lb rock is placed on a hill what will happen in 100 years?
Answer:The only change is atmospheric pressure on the rock if it is on a hill.Please refer to the question: http://wiki.answers.com/Q/What_will_happen_in_100_years_to_a_7_lb_rock ?The form of "a 7lb rock" in 100 years varies according to reactions:- Chemical Reactions:- chemical properties of the rock(i.e: includes salt),- the behaviour of the medium it is kept(i.e: humid or dry environment, solvent materials),- Physical Reactions:- External forces applied to the rock(i.e: acceleration),- Inertial forces of the rock. (i.e: surface tension).
How do you get the volume of an irregular and regular shape?
Any regular shape,like a cube or sphere, can be described mathematically and its volume can be calculated easily. An irregular shape, such as a rock can be mesured by displacment of water, or by scanning it in three dimensions.If the object's density is known, it need only be weighed. volume is a amount of mater space takes up TY!

How do you find the volume of the rock?
By its mass sweety. :) * * * * * It depends on the size of the rock. If you can lift it, find a container that is big enough to hold it. Put that container inside a collecting tray. Fill the container with water (or another liquid) to a level at least as high as the rock. Mark that level. Put the rock in the container gently. Measure the rise in the level of water and, if appropriate, collect the water that overflowed into the collecting tray. Calculate the difference in the two water levels. Add the overflow volume if appropriate. That sum is the volume of water displaced by the rock and so the volume of the rock. If the rock is too massive to lift or be contained in something you will need to estimate its volume. That can be done by profiling its shape and partitioning that into smaller, more regular shapes. Calculate the volumes of all those shapes and sum the answers.
