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.

Answer 1
What is seafloor spreading?

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)

Answers

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.

Which of the following equations follows the Law of Conservation of Mass?



2Na + Cl > NaCl



C + 4H2 > CH4



C2H4 + 3O2 > 2CO2 + 2H2O



3H2O > 3H2 + 3O2

Answers

Answer: C2H4 + 3O2 > 2CO2 + 2H2O

Explanation:

The law of conservation of mass has been given as the mass cannot be created nor be destroyed in a chemical reaction. The law of conservation of mass has equal weight of the reactants and the products.

The mass of following reactions can be given as:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

12g + 4(2)g   =   16g

20g = 16g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

3(18)   = 3(2) + 3(32)

54g = 102g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

2(23) + 36.5 = 58.5 g

81.5g = 58.5g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

The reaction that has been following the law of conservation of mass has been reaction 1. Thus, option 3 is correct.

Which of the following equations follows the Law of Conservation of Mass?

2Na + Cl > NaCl

C + 4H2 > CH4

C2H4 + 3O2 > 2CO2 + 2H2O

3H2O > 3H2 + 3O2

C2H4 + 3O2 > 2CO2 + 2H2O

The mass of the following reactions can be given:

28 g   + 3(32)g =  2(44)g  +  2(18)g    Mass

124 g              =   124 g

Thus, the reaction follows the law of conservation of mass.

The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
