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.
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.
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.

Answer:
carbon compounds
Explanation:
the series of processes by which carbon compounds are interconverted.
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Explanation:
so yeAH
b. a low-lying region where Precambrian rocks are covered by Phanerozoic sedimentary strata
c. a region of compressed rock located behind a volcanic arc at a convergent continental margin
d. synonymous with craton
Answer:
The correct answer is D. Synonymous with craton
Explanation:
Craton is referred to as a large immobile block of earth crust composed of ancient crystalline basement rock and have deep lithosphere roots that extends deeply into the earth's mantle.
Cratons are often seen as shields because the basement rock crops out at the surface, and in platforms, the basement is overlaid by sedimentary rock.
Geographically, a shield and a surrounding platform together are synonymous with craton.
As the Earth travels closer to Saturn in its orbit and then both planets are situated on the side of the Sun, Saturn is enduring an apparent retrograde movement period.
Even with a good telescope, it would be impossible to see against the background of stars. The parallax angle is the difference, measured from a nearby star, between the Earth's location at one point in time of the year and the Earth six months later. Astronomers use this angle to determine how far away from Earth that star is. The procedure outlined previously, s, can be used to determine the distance to a nearby planet. Now that we have established an observation point O, we can calculate the angle that the planet is at, which is. P1P2 = d, where d is the diameter of the planet. Consequently, we may apply the parallax technique to determine a neighbouring planet's radius.

Answer:
35°
Explanation:
j and 35° are vertically opposite angles so their measures are equal and 35° each.
