The driving force behind the movement of material from high to low areas if the force of gravity. But before that occurs, he rock material has to be broken (eroded), transported and deposited. This dynamic process is known as gradation and it is responsible for sculpting a variety of landforms.
1. They force water into cracks in the rock. That helps to break it up. It's called hydraulic action. 2. They dissolve soluble material from the rock. This is called solution. 3. They fling sand and pebbles against the rock. These wear it away like sandpaper. This is called abrasion.
Horizontal rock structure
A non porous rock is a rock which has interlocking grains so water can't get into it. A porous rock is like a sponge and a non porous rock is like a stone.
The refined minerals from rocks are used in automobile construction. Sulfur is used in tires, iron is used for many parts, feldspars and silicates for glass, bauxite for aluminum, and so on. Electricity used to manufacture the car may be provided by coal, an organic sedimentary rock.

Sedimentary rock: Limestone can be used as a building material, or fired in a kiln to produce powdered lime for scattering on a farmer's field. Sandstone can be used as a building material. Slate can be used as a roofing material and a building material.
It was a divot.
A foliated metamorphic rock is slate, which is used for roofing and flooring, but chalkboards are made of porcelain enamel (man made)
Slate is a sedimentary rock that can be split horizontally to produce smooth flat surfaces that is often used as a roofing material.
Roofing Material is a "Product" made for coevering your roof and protecting it from the elements
slate, it is also used in roofing
roofing material
Yes, because copper is a metal, and metals could be used for building things. In fact, copper is used as a roofing material.
