Geography

Before we carved pumpkins, the Irish chiseled creepy faces onto turnips. Pumpkins with ghoulish faces and illuminated by candles are a sure sign of the Halloween season. The practice of decorating jack-o'-lanterns originated in Ireland, where large turnips and potatoes served as early canvasses.

You watch a volcano erupt non-explosively, then 5 days later you see it erupt explosively.
alexdok [17]

D. high and low levels of silica in the different type of lava.

Explanation:

The volcanoes have different types of explosions. Some tend to be highly explosive, some less explosive, some don't have explosions at all, while some have combinations of different eruptions. The reason for this diversity in the eruption types is mostly the composition of the magma, or rather how high is the silica content in it.

Basically, the higher the silica level in the magma the higher the explosiveness, and the lower the silica level the lower the chances of explosiveness. This is the case because the higher amount of silica makes the magma thicker, so the gasses are trapped and they explode, while when the lower silica content makes the magma less thick, so the gasses are not trapped and explosions are lacking.

How can you explain rock evidence of Pangea?
otez555 [7]

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.
