Answer:
Explanation:
Rivers have three sections or courses: the upper course, middle course and lower course. The upper course of a river typically sees much erosion of bedrock in order to achieve the equilibrium mentioned above.
The upper course is also at the highest altitude as this is where the headwaters of the river originate. Rivers in the upper course erode down vertically which often creates a steep channel profile in what becomes the river valley.
The middle course sees a river at a slightly lower altitude than the upper course, but is still maintains a sense of trying to acquire equilibrium in flow and shape. The discharge and velocity of the river still allows the water to erode the banks and chart a course of least resistance through lateral erosion.
The lower course is unique as this is the stage in which a river has reached sea level. Here we find features not found in the middle and upper courses like floodplains and river deltas that have been formed by the sediment deposits of rocks and dirt gathered from upstream.
Answer:
The problem with this classification is clastic sedimentary rocks are not formed with organic elements, that is, they do not form with the remains of organisms, such as shells, for example
Explanation:
The student made an incorrect classification. This is because he classified a rock formed from shells as clastic sedimentary rock.
Shells are organic materials, as they are the remains of living organisms. Organic material is not capable of forming clastic sedimentary rocks, as these rocks are formed only by sediments. Remains of organisms, manage to form a type of rock called organic rock.

Answer:
Przyczyny marnowania żywności w Stanach Zjednoczonych i krajach wysoko rozwiniętych są następujące - zła pogoda, problemy z przetwarzaniem, nadprodukcja i niestabilne rynki powodują straty żywności na długo przed jej przybyciem do sklepu spożywczego, podczas gdy nadmierne kupowanie, złe planowanie i zamieszanie w zakresie etykiet i bezpieczeństwa przyczyniają się do marnowanie żywności w sklepach i domach.
