Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
Answer:
they occur at convergent plate boundaries
Answer:
Correct answer is Wegener had no compelling mechanism to explain what would cause the continents to move.
Explanation:
A is not correct as through his researches he presented his theory to other scientist.
B is not correct as Wegener was very educated, and was even even working as a professor at University.
C is correct that although he presented his theory, he couldn't explain totally how it happened.
D is not correct as during his lifetime his theory wasn't widely accepted. That happened 20 years after his death.
The more carbon dioxide, the more the atmosphere warms up due to the greenhouse effect.
Greenhouse effect- greenhouse gases trap the suns heat making the earth warmer
Answer:
The map shows the locations of divergent plate boundaries.
Explanation:
There are three main types of plate boundaries, divergent, convergent, and transform plate boundaries. They are defined in accordance with the interaction that the plates have between each other. At divergent boundaries the plates move away from each other, at convergent boundaries, they move toward each other, and at transform boundaries, they slide past each other.
On this map, we have marked the locations of the divergent plate boundaries. We have the divergent boundaries between the Eurasian and Africa plates on one side and North American and South American on the other side, between the Pacific plate and Nazca plate, and between the Pacific and Nazca on one side and Cocos plate on the other Last but not least, there is the divergent plate boundary between the Antarctic plate on one side and the Australian, African, and South American plates on the other sides.
