Answer:
Immediate drought impacts can include visibly dry vegetation and lower water levels in lakes and reservoirs. Longer-term impacts, such as land subsidence, seawater intrusion, and damage to ecosystems, can be harder to see, but more costly to manage in the future
Answer:
all of the above are factors
Explanation:
- Factors that impact or control the movement of magma and lava from the volcanoes include a wide array of factors like the composition of magma and lava which is viscous fluid that brings up the intensity of violent eruptions of such as those that have higher silicate content.
- The explosion intensity also depends on the volume and length of the eruption and composition of volcanic products and their eruption environment.
- The rooftop of the volcanoes i.e the upper chambers or vent is also seen as a major important factor controlling the opening of basaltic matter on the surface. In a shield volcano, the eruption matter is not that dense and vicious as compared to the Italian and strombolian volcano that have a high intensity of lava flows.
Answer: Outlet glaciers
Explanation:
Outlet glaciers fall under the Ice Sheet classification of glaciers whilst the rest listed above fall under the Alpine Glacier classification.
Outlet glaciers derive their name from their characteristic of flowing out of glaciers like ice sheets and ice caps.
The difference between Ice sheets and Alpine glaciers is that the former smoothens the terrain while the latter steepens it.
Answer:
By a mix of human and physical geographic evidence.
Explanation:
Civilizations can end due to natural causes. Volcanic eruptions can be devastating for people living close to it. Checking rock age and strata with any historical references could explain. Data from ice core could indicate changes in the atmosphere. A change, such as increased drought, in regions, might end up causing food shortages and the end of civilizations.
Human evidence can provide the answers too. Migration patterns may explain this, such as the Europeans arrived in the Americas. The land has a carrying capacity. Studying the population might indicate the carrying capacity was exceeded, such as Easter Island.
Answer:
The lower rocks are old while the overlying is newer.
Explanation:
- Red sandstone is overlain by a red shale with bedded gypsum sows the age of the rocks. The boundary in the rock bodies for about 1km marks the along the fault displaced the two rocks bodies.
- As 50 meters, thick red sandstone is found it shows the discontinuities in the rocks. The rocks formed at the bottom are oldest and with newer deposits of gypsum.
