How do you think Earth's large temperature gradient affects the speed of its convection currents? How would this speed change if Earth's core were cooler?

Answers

Answer 1
Answer:

Answer:

Convection currents in the Earth's core are caused by hot magma rising upwards, cooling, then sinking back toward the core. These convection currents are the driving force for tectonic plate movement in the crust. The constantly moving magma in the mantle carries the plates sitting on top of it. The hotter the magma, the faster the speed of its convection currents.

If the interior of the Earth were to cooler, then the movement of the plates would decrease.

Answer 2
Answer:

Answer:

A higher temperature gradient causes faster heat transfer, and thus faster convection currents. If the core were cooler, the temperature gradient would be lower, so the convection currents would likely slow down.

In geology, the term "transform fault potential" denotes the extent to which one tectonic plate could be moved along a major transform fault line, such as California’s San Andreas, by an instantaneous strain release, commonly known as an earthquake. (A) the extent to which one tectonic plate could be moved
(B) the extent to which one tectonic plate could move
(C) the extent that one tectonic plate could be moved
(D) the extent of one tectonic plate moving
(E) the extent of the movement of one tectonic plate

Answers

Answer:

(A) the extent to which one tectonic plate could be moved

Explanation:

  • The transform fault is a zone where the two plates slide past one another and thus the result in the displacement of the large landmass. Due to the presence of the earthquakes and the formation of thin valleys and the splitting of the river beds such as in the San Andreas fault.
  • And the transform fault potential is the potential that the tectonic plates can e be moved to the extent that the earthquakes can occur. The transform fault is found in the oceanic basin and is offset by the mid-oceanic ridges.
  • Thus they form an interactive zone of the dextral zone of the plate movements.

I have an awful time trying to understand poems and stories before the 1900's, so i need assistance understanding one of the possible answers in this question i was given. "Which trait is common to the narrators in these excerpts?" The first story that is given is called "Captain Singleton" By Daniel Dafoe "At this juncture comes by one of those sort of people who, it seems, made it their business to spirit away little children. This was a hellish trade in those days, and chiefly practised where they found little children very well dressed, or for bigger children, to sell them to the plantations. The woman, pretending to take me up in her arms and kiss me, and play with me, draws the girl a good way from the house, till at last she makes a fine story to the girl, and bids her go back to the maid, and tell her where she was with the child; that a gentlewoman had taken a fancy to the child, and was kissing of it, but she should not be frighted, or to that purpose; for they were but just there; and so, while the girl went, she carries me quite away." The second story is called "Moll Flanders", also by Daniel Dafoe "However it was, this they all agree in, that my mother pleaded her belly, and being found quick with child, she was respited for about seven months; in which time having brought me into the world, and being about again, she was called down, as they term it, to her former judgment, but obtained the favour of being transported to the plantations, and left me about half a year old; and in bad hands, you may be sure. This is too near the first hours of my life for me to relate anything of myself but by hearsay; it is enough to mention, that as I was born in such an unhappy place, I had no parish to have recourse to for my nourishment in my infancy; nor can I give the least account how I was kept alive, other than that, as I have been told, some relation of my mother's took me away for a while as a nurse, but at whose expense, or by whose direction, I know nothing at all of it." Now, i can't find which of these answers would best fit the question, because i get so easily lost in the writing style. Available Answers (They allow me to only pick one by the way.): -The narrators were born in poverty. -The narrators were separated from their birth parents. -The narrators grew up to be criminals. -The narrators worked hard in life to improve their social status. -The narrators blamed themselves for their misfortunes.
