The statement is correct.
The contour lines are a very good indicator of the relief. The closer they are to one another, the steeper the relief, and vice verse, the more distant they are from one another, the flatter the relief is.
In general, contour lines that are very close to each other can be noticed on the mountains, as most of the mountains have steep parts, or rather steeper slopes.
The more distant contour lines, on the other hand, can be found on places like the valleys or the plateaus, places that in general are much flatter.
i. Using fossil evidences
ii. Similar rock lithologies at the edges of continent
iii. Climate clues
iv. Fitting of the continents into a puzzle
v. Sea floor spreading
Explanation:
Pangea was a super-continent on the earth which formed about 330 million years ago during the Paleozoic and began breaking up during the early Mesozoic, about 175 million years ago.
Most of the present day continents formed as a result of the separation of the Pangea in the early Mesozoic.
The first scientist to propose the existence of this super-continent was Alfred Wegener in 1912. He suggested the continental drift hypothesis to explain the separation of the land masses.
Today, the theory has been revised to the theory of plate tectonics which provides a better mechanism to understand the drifting of the continents.
Here are some of the evidences to support the existence of Pangea;
- Using fossil evidences: Mesosaurus, a reptile animal that lived during the Permian, was found in both South America and Southern Africa. Since this animal could not swim nor fly, only a jointed landmass could have made them present in both continents.
- Similar rock lithologies at the edges of continents: rock formations at the Western edge of Africa and South - Eastern part of Brazil matches with one another and have been believed to be once joined together.
- Climatic clues such as glacial tills that are confined to temperate and polar regions have been found in tropical regions.
- Wegener fitted the present day continent into a giant supercontinent and this provided a visual support for his claim.
- Evidences from sea floor spreading revealing magnetic reversals at divergent margins suggests the prevalence of plate tectonics i.e moving plates on earth.
This among many other evidences underscores the existence of a supercontinent called Pangea.
<h2>Broken down of soil particles by the processes of weathering and erosion, carried by the action of wind, water, ice or by the force of gravity acting on the particles.</h2><h2 />
Explanation:.
Sediment enriches the soil with nutrients and rich in biodiversity. This soil works great for farming. The deposition of sediments makes the agricultural areas like deltas and river banks more fertile.
Glaciers carry a huge range of sediment with several sizes. With continues deposition, space for the animal and plant life gets reduced.
The most dangerous part is that the animal’s may suffocate and intervention may occur with their food intake.
