Is this a good answer?

Notice that at the divergent boundary, the crust is experiencing tensional stress, which is causing a normal fault that results in seismic activity, and that the volcanic activity is caused by upwelling of mafic lavas from the mantle. On the other hand, convergent boundaries are the result of compression stresses leading to plate collisions, which create numerous thrust and reverse faults that are responsible for seismic activity. Volcanic activity at convergent boundaries is created by andesitic lavas produced by the partial melting of a subducting plate. Which features and characteristics associated with divergent boundaries and which not, will you determine?

Answers

Answer:

In a divergent plate boundary, two plates move away from one another. Due to this divergent movement of plates, seafloor spreading takes place in the ocean basin along the mid-oceanic ridge and rifting take place in the continental areas. Due to the stretching of the crust, the lithosphere becomes thin, and with more progressive spreading, it results in the eruption of magma at the seafloor. This magma is basaltic in nature, that reaches the surface due to the force exerted by the uprising magma forming convection cells in the mantle. This type of plate motion results in the expansion of the ocean basin and the rift valley in the continental areas forms seas and oceans with increasing time.

The rocks that are formed at the mid-oceanic ridge are the youngest as the magma cools and solidifies very rapidly here. With further moving away from this spreading center the age of the rocks increases.

The divergent plate boundaries are also responsible for the occurrence of deep-focus earthquakes, and it also leads to the formation of volcanoes in its adjacent sides.

Final answer:

Divergent and convergent boundaries exhibit different features and characteristics. Divergent boundaries are associated with tensional stress, normal faults, and volcanic activity from mafic lavas. Convergent boundaries experience compression stress, create thrust and reverse faults, and exhibit volcanic activity from andesitic lavas.

Explanation:

Divergent boundaries are characterized by tensional stress, resulting in normal faults and seismic activity. This type of boundary is also associated with volcanic activity caused by the upwelling of mafic lavas from the mantle. On the other hand, convergent boundaries are the result of compression stresses, leading to plate collisions. These boundaries create thrust and reverse faults and are responsible for seismic activity. Volcanic activity at convergent boundaries is caused by andesitic lavas produced by the partial melting of a subducting plate.

Question 21 1 pts Which of the following is NOT a common type of isoline? O isogrids O isohyets O contour lines O isotherms O isobars

Answers

Answer:

Option (1)

Explanation:

Isohyets- This are the lines that connects the points of equal amount of rainfall that occurs at any given period of time.

Contour lines- This are the lines of equal elevation.

Isotherms- This are the lines that connects the points of equal temperature.

Isobars- This are the lines connecting the points of equal atmospheric pressure.

Isogrids- This are a type of half hollowed-out structure that is created mostly from a single metallic type of plate with hard triangular rib like structures that are commonly known as stringers. This are very light and hard in comparison to other substances, This are very costly to build, so they are basically used for the applications that are usually related to the spaceflight and also used in the field of aerospace.

Thus, the isogrids are not a common type of isoline.

Hence, the correct answer is option (1).
