Answer:
c. fracture zone.
Explanation:
Continental margin is said to be the connection between the oceanic crust and the continental crust. Continental margin separates the sea floor from the continental crust.This margin is usually the shallow region that approaches the continental crust.
All the following options are parts of a continental margin except Fracture zone which is a weakness in the earth crust that cut across the mid oceanic ridges.
Continental shelf extends from the edge of the continent towards the sea floor and are shallow in nature. This portion of the continental margin transition from the continent to the sea. They are gently inclined and typically flat.
Continental slope extends from the continental shelf to the depth of the oceanic floor. continental slopes are relatively steep.
Continental rise exist at the foot of the continental slope and they are located between the continental slope and the abyssal plain(A flat plain at the base of continental rise).
Submarine canyon are valleys that runs across continental shelf down the continental slopes.
The Mexican Revolution was a huge rebellion that occurred from 1910-1920.
I don’t know, but I hope you get the answer your looking for :)
No, it doesn’t occur in
the same organelle or organism. Chloroplast is the organelle where Photosynthesis
occur, while Mitochondria is the organism/organelle where cellular respiration occur.
Photosynthesis happens in the plant kingdom called for example a sun flower
uses the process of photosynthesis to make food for itself. Cellular respiration
is a chemical process in the mitochondria that makes energy out of sugar and
oxygen creating ATP.
Answer:
C. Magma from venus mantle erupted as lava.
Explanation:
A volcano is a landform which results from the eruption of molten rocks (lava) on the surface. Volcanic rocks are a special type of igneous rock that forms when molten rock cools and solidifies on the surface.
From the little description given, option C gives the best scientific explanation to the occurrence of the volcano on the surface of Venus. For a planet like venus which is presently not active and little to no movement occurs within the plates, the volcanisim must have occurred when the planet was relatively young and it must have been millions of years ago.
It is widely believed that Venus was geologically active in times past. Mantle generated lava must have solidified on the surface in times past to have formed the volcano.
Evaluating other options:
... Impact of space objects on Venus would lead to the formation of a crater which is a depression on the surface. The rock would be mostly metamorphic.
.... If water was ever present in Venus, they would have produced sedimentary rocks instead. The erosive power of water is not high enough to cut through the crust. Also, water would not aid the formation of volcanoes.
.... Heat is not enough to from volcanoes. Other factors are also in play.
