Restricted usage of the advanced technologies. The low farm productivity can be improved by having a better mechanization, an effective agricultural infrastructure, etc.
Explanation:
Answer:
It helps with stratigraphic studies.
Explanation:
Bedding planes are the sheets that distinguish each successive layer of a stratified rock from its preceding layer, also known as sedimentary planes or stratification planes.
When one layer of sediment that is completely different from the former is formed or created over the old layer, bedding is said to have occured. This new layer may comprise of sand and tiny stones (called pebbles) or other sedimentary material. Because the components of the each new successive layer are totally different from the former in terms of composition, there is a marked division between each of them identifable by their quality and colur.t
The study of each of these layers to ascertain their time scale which provides basis for studies in historical geology is called stratigraphic studies.
The initial placement of strata in geologically diverse terrains is suggested in stratigraphical studies and the depositional nature of the sediment is established.

Answer:
Cobble is a big piece of stone whereas clay is the smallest particles of earth.
Explanation:
Cobble is a small round stone used to cover road surfaces. Pebbles are the round rock fragment with a diameter of 4-64 mm which is smaller than a cobble but larger than a granule. Sand is a loose granular material that produces from the disintegration of rocks, the particles of sand is smaller than gravel. Its particle size is 0.0625 to 2 millimeters. Silt is granular material having a size between sand and clay about 0.002 to 0.05 mm. Clay is a stiff, sticky fine-grained particles that can be molded when present in wet condition and is used to make bricks, pottery, and ceramics. Clay particles are smaller than 0.002 mm in diameter.
