law is any concept that is true and real while theory is a concept which nobody can tell weather it is true or false
for eg :
Law- every action has equal and opposite reaction
(It is law because it is proven)
Theory- Big bang theory
(no one no it true or false)

Explanation:
The flow of the river is dependent upon the position along the stream in terms of the gradient. Near the top of a high gradient, the flow will be less than that near the bottom. Likewise, the steeper the river's gradient, the faster the flow of water (due to the pull of water down the gradient by gravity).
Explanation:
Observations allow us to collect data that we can connect back to the central problem. From this data we can start to form hypotheses (predictions on possible solutions or outcomes).
Answer:
The correct option is;
Sand, clay, and silt
Explanation:
The categorization of soil particles by size can be made into three classes including sand (particle size between 0.05 mm to 2 mm), silt, (particle sizes between 0.002 mm to 0.05 mm) and clay (particle sizes lesser than 0.002 mm), larger particles such as stones, pebbles, boulders and rock other fragments are left out of the textural classification because of their inertness
The combination of the three particle sizes can be found in most soils and their relative proportion defines the texture of a given sample of soil.
