Fossils of Glossopteris, an extinct fern, were discovered on which continents to support the theory of continental drift? Check
Alenkasestr [34]

Accordin to Du Toit's list supporting the theory of continental drift, the correct options are A, C, ad D. <em>Fossils of </em><em>Glossopteris</em><em> were discovered on </em><u><em>Africa, Australia, and Antarctica</em></u><em>. </em>

--------------------------------

Before answering the question, let us first review some theoretical frameworks,

• The tectonic plates theory explains the movement of the different plates based on the crust movements.

• The continental drift theory explains how these movements have been taking place for millions of years.

Alfred Wegener was the first one to state the concept of continental drift.

He proposed that once all continents were together a single big continent named Pangea, and with time, they split and separated into many pieces.

The geologist Du Toit published in 1937 a list of 10 pieces of evidence that would support the theory of tectonic plates and continental drift.

Du Toit's list includes evidence of <em>Gondwana glaciation, lithological and structural evidence, plates fitting together, and paleontological evidence</em>.

Paleontological evidence

• Plant and animal fossils distribution suggests the existence of a big unique continent. When reconstructing the supercontinent, the areas where these fossils were found get together in the same supercontinental region.

• Glossopteris (fern) impressions are widely distributed in determined areas of Africa, South America, India, Australia and Antarctica.

• Terrestrial vertebrate fossils also support the theory. The presence of Triassic tetrapods in all continents suggests terrestrial corridors between landmasses.

Finding Glossopteris in Australia, India, South America, Antarctica and Africa suggests that continents were once together, and these species used to live in the same region.

With time, these continents diverged and got separated by the oceans. The region where Glossopteris used to live got divided.

<em>The correct options are A, C, and D. Africa, Australia, Antarctica.</em>

Why might someone want to have smoke in the air at a laser show
levacccp [35]

Answer:

Someone wants to have smoke in the air at a laser show because It's the dust particles or mist droplets which reflect the light of the laser. When you see a laser beam, what you are seeing is the beam being scattered by various small particles suspended in the air. ... When people want to show off laser beams, they often add smoke or equivalent to the air.

What are the two factors that define our traits?
coldgirl [10]

There are a few theories as to what defines our traits to create our personality

According to one such theory, Dan P. McAdams claims our personalities develop in <span>three </span>stages:

<span>Our genes cause genetic mutations forming a 'draft' personality.During our early upbringing, our parents, teachers and friends treat us differently based on our looks and draft personality.Once we are older we then form a narrative of our lives based on our experiences growing up, and make decisions consistent with the character we have created.</span>

So our traits started from slight genetic variances, which effected how we were treated, which then shapes our own self-narrative. So really, our personality is one big story that we tell ourselves, and our childhood was the prologue to that story.
