Answer:
Earth's sedimentary rock can be explained from the crustal plates on earth.
Explanation:
- Earth's most sedimentary rocks are formed in continental or land crust as the oceanic crust is made up of heavier materials such as basalt and has a density of 2.9g/cm cube.
- The tectonic forces that originate deep within the earth layers and the arrange of rocks found at greater depths which are responsible for the density and thickness of the continental land crust are volcanism and earthquake activity.
- Igneous and metamorphic rocks that form along with the sedimentary rocks in the earth's crust and areas of shallow beds close to the shores of continental shelves are of less density and less thickness and those submerged beneath this layer are those of higher mass and density.
- About 40 % of the earth's surface and 70 % of the continental volume is dominated by the earth's crust of terrestrial in origin. In due course of time, the mountain upliftment and isostasy formations have developed the crustal thickness.
Volcanic soil has a lot of minerals that plants take in as nutrients.

Answer:
Issues involve in inferring with the overall regional direction of ice flow.
Explanation:
Ice sheets are a thick boundary of ice mass moving at the rate of 2 or 3 cms per year. The implications of the current climate change on ice sheets are difficult to ascertain. Increasing temperatures are resulting in reduced ice volumes globally. Rising in sea levels increases the ice flow and the increase in global temperature takes place through the ice melt. Also, the regional changing wind speeds around the glaciers like in Antarctica have speeded the meltdown. Consequently, the erosion takes place on a large scale. A rise in temperature and the reduction of freshwaters creating more saline conditions around many regions of the world. Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools.
