Answer:
b less dense and thicker under the continents than under the oceans
Explanation:
- <em>Oceanic crust </em>is found under the ocean, it's about 6 kilometers thick and is destroyed in subduction zones just like the continental crust. It's composed of several layers and it differs from continental crust because it's thinner, denser, younger and with a different chemical composition (olivine, pyroxene, and amphibole).
- <em>Continental crust</em> is thicker (100 kilometers) and less dense than oceanic crust, it resists subduction and its age is 30 times the average of the ocean's age.
Considering this information we can conclude that the correct asnwer is: b less dense and thicker under the continents than under the oceans.
I hope you find this information useful and interesting! Good luck!
Hypothesis: An educated guess on the natural world possibilities
Theory: An explanation of the natural world aspect
Law: An aspect of how the natural world reacts under a specific circumstance
Hypotheses, theories, and laws all have natural world tests in common. Each of them are trying to provide the steps to guarantee a valid experimentation. You cannot have a valid experimentation without each of these. However, fact is also a need.
Every 85 years it shows it is expected in 2061
Convection occurs in fluids (so both liquids and gases, as well as rheids) and is the concerted, collective movement of groups or aggregates of molecules within the above through advection or diffusion or both at the same time. Convection can never take place in solids and is only specific to fluids.
