Answer:
Mercator
Explanation:
The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because of its unique property of representing any course of constant bearing as a straight segment.
Answer:
Alfred Wegener presented numerous observations in his Theory of Continental Drift, some of which are given as under.
Explanation:
- Wegener gave his continental drift theory as the founding stone in the history of the evolution of geologic time of the earth 1912, and suggested that there existed large landmasses on history of earth surface as in the form of Pangea, two major super landmasses, and Laurasia as the northern landmass which led to the formation of North America and Northern continents around the world.
- The southern landmasses consisted of Gondwana and included the southern parts of landmasses like South America, Africa and Antarctica along with Australia.
- The evidence that he gave where in the form of jigsaw fit amount the continents South America and the coastlines of Africa, the finding of same mountain chains and ranges around different parts of the world.
- The presence of various plants and animals like the lemures and glossopteris flora were found in the bottoms of the Atlantic ocean as they tended to move westwards.
- Another evidence he gave was the findings of similar climates around the world that were associated with the movement of plates and also gave importance to the ocean currents and movement of crust under the force of gravity.
Belize City (Spanish: Ciudad de Belice) is the largest city in Belize and was once the capital of the former British Honduras. According to the 2010 census, Belize City has a population of 57,169 people in 16,162 households.
Answer:
The characteristic of the depositional environment affects the properties of sedimentary rocks are as follows-
(1) <u>Lithology-</u> It describes the constituent mineral and the type of texture these crystals have, which forms a sedimentary rock. These minerals occur in a certain depositional environment. When the weathered materials are derived and transported to some other place, then it forms a stable one in a fixed environment as the rocks are subjected to compaction and lithification, The environment in which these minerals have led to the formation of these rocks can be determined.
(2) <u>Structure-</u> There are various structures that occur in rock, such as ripple marks, cross-bedding that highlights the flow direction of water and wind. Many structures like slickensides, folding, faulting occurs in the sedimentary rocks that are formed due to tectonic activities. These structures can easily be identified and their environment of deposition can also be determined.
(3) <u>Fossil content-</u> Fossils are found to be embedded in the sedimentary rocks. The shells of organisms after death are accumulated at the bottom of the ocean. As a result of this, these shells are covered with the sediments and after millions of years, turn into fossils. For example, Sandstone, Limestone, and shale comprised of various types of shells. These fossils are found to be deposited in a shallow marine environment.
