Answer:
A. = Shale
B = Granite
C = Sandstone
D = Limestone
Explanation:
Based on the weathering patterns, the rock type shown in each photo can be concluded to be as 
A. = Shale: this is a form.of sedimentary rocks. It is formed from finely textured materials. Such as clay, quartz, and calcite minerals
B = Granite: this is derived from igneous rock. It has coarse texture features. 
C = Sandstone: it is formed by a sand-sized grain of natural earth materials that form together
D = Limestone: it is also a form of sedimentary rock. It contains a large quantity of calcium carbonate it is formed from materials such as ancient corals and skeleton.
 
        
             
        
        
        
Answer: The atoms in a gas move at high speed.
The atoms in a gas spread in all directions.  
A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.
