Reasons why the study of geography is important and how it affects your life

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;

1. 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.
2. 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.
3. Climatic clues such as glacial tills that are confined to temperate and polar regions have been found in tropical regions.
4. Wegener fitted the present day continent into a giant supercontinent and this provided a visual support for his claim.
5. 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:

Saskatchewan

Explanation:

I think the answer is Saskatchewan.

Final answer:

The Canadian province with straight lines or 'borders' all the way around it is Saskatchewan. It is almost completely defined by straight lines of latitude and longitude.

Explanation:

The province of Canada that has straight lines all the way around it is Saskatchewan. Canada is divided into 10 provinces and 3 territories.

Provinces are regions within Canada boundary defined by longitudes and latitudes, contours of natural elements such as mountain ranges, rivers, and lakes, or straight geometric lines.

Saskatchewan is one of the few that is almost completely defined by straight lines of latitude and longitude, giving it its rectangular shape.

Final answer:

The prominent feature in the central Atlantic Ocean is the Mid-Atlantic Ridge - a rifting zone where tectonic plates are pulled apart and filled with molten rock or basaltic lava, forming a ridge. This ridge spans the entire Atlantic Ocean.

Explanation:

The prominent feature found in the central Atlantic Ocean is known as the Mid-Atlantic Ridge. The Mid-Atlantic ridge is termed a rifting zone, where tectonic plates are pulled apart from each other. This separation is driven by upwelling currents in the mantle.

When the plates separate, a space is created which is filled with molten rock or basaltic lava that rises from beneath, forming the ridge. This process of the oceanic crust creation is known as seafloor spreading.

The Mid-Atlantic Ridge stretches across the entire Atlantic from the Arctic to the Antarctic regions, and it is a particularly prominent topographical feature of the Atlantic seafloor. This phenomenon is also closely related to the phenomena of earthquakes and volcanoes.
