Definition of erosion (according to National Geographic): “Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.”
1. Describe the features that water erosion produces in your images (mountains, canyons, deserts, etc?) What do they have in COMMON?
Mountains: Water erosion would create a waterway around the mountains.
Canyons: Water erosion would create more area between the canyons.
Deserts: Water erosion would generally change the desert’s landscape by making the hills more downslope.
What they have in common: They all create changes to the landscape of different areas.
2. You can see water erosion even when you do not see water. How is this possible? Be clear!
This is possible by rain?
- I’m not exactly sure about this question.
Answer:
A human community with high population density and low economic status will have the highest birthrates.
Explanation:
A is not correct because usually, these are populations in countries that are transitioning from one political to another political model, and these populations actually tend to decline, mostly because of immigration.
B is not correct because such populations tend to have low birthrates, often even below the bar for simple replacement of the population.
C is not correct because such populations tend to live in very bad conditions, so despite having relatively high birthrates, they stagnate in their growth.
D is correct because such populations have both the numbers needed and also live in more traditional societies, leading to very high birthrates, as can be seen with Nigeria, Ethiopia, Pakistan, Indonesia, etc.
“The vast majority of Egyptians live in Egypt where they constitute the primary ethnic group at 97-98% (about 76.4 million) of the total population. Approximately 90% of the population of Egypt is Muslim and 10% is Christian (9% Coptic, 1% other Christian).”
