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.
Answer:
territory, place, region and landscape
Explanation:
The main categories of geographic analysis basic concepts are :
<u>Territory</u> :
The meaning of 'territory' is a delimited space or region. These delimitation occurs across the borders which is either defined by the nature or defined by man.
<u>Place</u> :
It is mainly used by the people who prefers to build the comprehensive conception of Geography. It is defined as a certain area or land that are understood by the human reason. It is a perceived space.
<u>Region</u> :
It is defined as the space or an area which are divided according to specific criterion. It is the normal human elaboration or idea to better understand some certain area.
<u>Landscape</u> :
It is defined as the external configuration of a space. It is the spatial phenomena and manifestation which are apprehended by a human through the senses.
The one answer that I am missing among the options, but which is the correct one is: the geography of the region ( I assume that that's what was instead of the "7" in the first option).
It was very mountainous, with valleys and islands on which people lived -meaning there was a natural separation between the different settlements.
