Hi! I’m working on a lesson and need some clarification. Can someone give me the gist of what seafloor spreading is? I understand it, just wanted to clarify! Thank you!
Oh, and I kinda need this answered within 20 minutes please.
Seafloor spreading is simply the idea that volcanic activity forms new oceanic crust.
In order to understand what seafloor spreading is in depth, it's important that we understand a few concepts and terms.
What are divergent boundaries? - In plate tectonics, divergent boundaries are tectonic plates that move away from each otherHow are volcanoes formed in divergent boundaries? - As plates move away from each other, magma risesWhat is the mid ocean ridge? - The mid ocean ridge is a continuous range of underwater volcanoes that wrap around earth.What happens when magma touches water? - When magma touches water, it cools and eventually hardens.If we can understand these terms, we can easily comprehend what seafloor spreading is.
If we take a look at the attached image, the image represents what occurs during sea floor spreading. First we must note that sea floor spreading occurs in mid ocean ridges. Because we know that mid ocean ridges is a continuous range of underwater volcanoes , we know that the mid ocean ridges are formed on divergent boundaries (as volcanoes under water are formed by divergent boundaries) . As we know, at divergent boundaries, the tectonic plates move away from each other. As the tectonic plates move away from each other, magma pushes itself up and as the magma touches the water it cools and hardens forming the crust as shown in the image. (Note that this takes several years to happen)
What is a disadvantage for organisms that reproduce asexually rather than sexually?
Responses
The offspring receive less genetic material.
The offspring receive less genetic material.
The offspring take more time to grow and develop.
The offspring take more time to grow and develop.
The offspring resemble the parent, which makes it difficult to distinguish them from each other.
The offspring resemble the parent, which makes it difficult to distinguish them from each other.
The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
Answer:
The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
Explanation:
If there was a disease (as an example) that negatively effected both organisms that reproduce asexually and sexually, the organisms that reproduce asexually would have a disadvantage. Offspring of the organisms that reproduce sexually contain the genetic material of both parents. This would lead to a higher chance of the ability to adapt to any changes, or even a chance of being immune to that disease. However, offspring of the organisms that reproduce asexually are only replicates of the parent. This means that the asexually produced offspring and the parent organism could be harmed more than the sexually produced offspring and parent organism. The organism would have reduced abilities to adapt according to the changes in the enviroment.
The major disadvantage for organisms that reproduce asexually is option 4 that the offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
Asexual reproduction is a type of reproduction where only a single parent is involved in creating offspring. The offspring reproduced are genetically identical to the parent. while this form of reproduction has many advantages including rapid and quick reproduction, it posses some major drawbacks as well.
As the genetic diversity is absent in asexual reproduction, adapting and surviving in the dynamic environment is tough for the offspring. Difficulty in catching up with the changing circumstances can sometimes lead to harm to upcoming species.

Argument 1
The water in the puddle that Claire observed evaporated. The highest temperature was 32°C (90°F). Since the puddle was there in the morning and gone later in the day, it must have evaporated.
Argument 2
The water in the puddle that Claire observed evaporated. Since the highest temperature was 32°C (90°F), we know that it was a warm day. When water gets hot, it can change from liquid to gas. This is called evaporation. I think the water became so warm that it became water vapor (gas), and that’s why the puddle was gone by the afternoon.
