Answer:
A
Explanation:
Isostatic equilibrium is used to state why some regions of the lithosphere have greater elevation than others. The crust ‘floats’on the‘liquid’ mantle below and different regions of the crust submerge into the mantle differentially depending on their local densities or weight. Heavier regions such as in mountainous region (like the Himalayas) are sunken deeper into the mantle that other regions. Every local region has its own local isostatic equilibrium.
Answer:
The correct option is Option C
i.e. Asthenosphere is denser than lithosphere.
Explanation:
Asthenosphere is the layer situated below the lithosphere.
Theory of isostasy says that the layers above the other layer must have lesser density. This has two explanations. Firstly, if its not hold, then the denser above layer would sink below the less denser bottom layer. Secondly, as we go inwards, the pressure increases. This leads to the lower layers have greater density. So, as Asthenosphere is situated below the lithosphere, it has higher density.
Answer:
Octopus and butterflies and shrimp don't follow Carnegie stages. But Turtles and Elephants do. Hope this helps!
Explanation:
The correct answer is that a butterfly and an octopus do not have Carnegie stages of development, while elephants and turtles do. This is because Carnegie stages of development are stages found only in the development of the vertebrate embryo. Carnegie stages can be defined as a system in embryology, which include 23 stages of the embryonic development, each characterized with the different age, size and morphologic characteristics of an organism.
Explanation:
The gradient of slope – the steeper the gradient the higher the velocity
the shape of river channel – the more straight the channel (with fewer meanders) the higher the velocity
The volume of water that the river carries – The more water the higher the velocity because more water has more mass that carries more momentum.
The roughness of the substrate or stream bottom – The rougher the river bed is, the slower the river water velocity due to increased turbulence and less laminar flow
The depth & width of the stream – The narrower and deeper the river channel the higher the velocity. This is because the water has a lesser surface area to rub against the river bed as it flows hence gains higher speeds due to lower friction.
