Why does sedimentation continue to fill the basins, albeit typically rather slowly, during the post-rift phase?
Bond [772]

Answer:

Subsidence is so slow that there seems to have been no depression of the upper surface of the lithosphere, so depositional environments are mostly the

same as those in surrounding areas; the succession is just thicker. These

successions are also more complete, however—there are fewer and smaller

diastems—so at times the basin must have remained under water while surrounding areas were emergent. (A diastem is a brief interruption in

sedimentation, with little or no erosion before sedimentation resumes.)

Size, shape: rounded, equidimensional, hundreds of kilometers across

Sediment fill: shallow-water cratonal sediments (carbonates, shales, sandstones),

thicker and more complete than in adjacent areas of the craton but still

relatively thin, hundreds of meters.

Hopefully that helps!

Write about mesosphere and Ionosphere​
lora16 [44]

Answer:

1. The mesosphere is very important for earth’s protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth’s surface. The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapour in its atmosphere into ice clouds.

2. the layer of the earth's atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves. It lies above the mesosphere and extends from about 50 to 600 miles (80 to 1,000 km) above the earth's surface.
