Answer:
The grain size
Explanation:
The grain size can provide lot of clues for us when it comes to the formation of the rocks, the conditions in which they formed, and even what happened after their initial formation. The reason for this is that the grains vary in size and shape depending on the conditions in which the rocks formed. If the magma/lava cooled of quickly, the grains will be very small, almost unnoticeable, and that is a sign that the cooling appeared on the surface, very close to it, or in the presence of water. On the other hand, if the magma cooled slowly, the grains will be large and well defined, and that is a sign that the magma was cooling off slowly, deep into the crust, where there's higher temperature and pressure.
Answer:
Areas or regions with low sea level or at sea level are called lowlands.
Lowlands are formed by deposition of lava through water, wind, or soil erosion and it has been said that such plains are more fertile for farming as compared to other high sea-level plains.
At Lowlands, people get opportunities for employment and the economy of the nation can be boosted.
For example, Lowlands of Scotland.
Farmers growing paddy or rice are getting the main benefits of Lowlands.
Lowlands have a suitable environment for many agricultural products.
Farmers can develop dairy farms and mountain farms.
Answer:
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life "rode" on diverging plates, became isolated, and evolved into new species
Answer:
