Answer:
The correct answer is the Hydrosphere.
Explanation:
The hydrosphere is the water that supports various life forms, the sphere plays a crucial role in our ecosystems and regulates the atmosphere. The Hydrosphere also covers all water present on the surface of the earth.
Answer:
Option (D)
Explanation:
The East African Rift valley is one of the best examples of the divergent plate motion. Here, the Somalian and the Nubian plate is moving in the opposite direction at a rate of about 5-7 mm every year. This rift started to form since the Oligocene Epoch. The formation of a rift valley is the starting of the continental separation and it eventually leads to the formation of seas.
This rift valley is currently an active rift, where the convection current is forcing the plates to move apart. The mantle plumes beneath this region are forcing the lithosphere to rise up and weakens it by stretching and breaking further by creating faults in its nearby places. In addition to this, volcanism also occurs adjacent to this type of plate motion.
These rift valleys are formed due to the<u> tensional stress (force)</u> that allows the plate to move in the opposite direction.
Hence, the correct answer is option (D).
Answer:
But at the same time, they have great importance economically. So, energy resources derived from natural organic materials are called fossil fuels.
Answer:
Positives -
- There becomes a higher consumption of certain foods and drinks (a boom-time for ice-cream and cold drinks)
- Domestic tourism is having a boon with "stay-cations"
- Measured industrial output rises, hence GDP rises, because of increased use of electricity
Negatives -
- Heatwaves can cause a surge of dry weather. This could lead to Droughts and could have a negative impact on locals. Crops for farmers could dry out, and there could become a lack of vegetation (for animals too).
- Higher death rate for people with certain conditions (e.g. more heart attacks, especially among-st elderly people)
- Reduced numbers for certain forms of entertainment (ie cinema etc)
