Answer:
C. Trees with thin trunks
D. Fewer species of plants
Explanation:
If a forest has been logged once and regrew, that is a second-growth forest. Some characteristics:
- Thin tree trunks
- Fewer species of plants
- Little light reaching the forest floor
- Very high density of trees
Variations in air pressure from place to place are the principal cause of wind.
Answer:
Option B
Explanation:
The higher the solute concentration the higher is the density of the solution. Hence, water with high salinity will have high density.
Hot water has energized atoms and molecules which increase fluidity of water as viscosity is reduced. On the other hand cold water has high viscosity and hence it is denser than hot water.
Thus, Water having high salinity and low temperature will be more dense.
Answer:
B, C, and D
Explanation:
As the question says, a GPS finds exact locations. Exact locations have nothin to do with when something happened.
It is clear that from 2006 to 2012, the average insolation reflected by the Greenland ice sheets is decreasing. This indicates that each year, the amount of solar radiation that the ice sheets are able to reflect is decreasing. The level of insolation reflected is dependent on the area of ice sheets capable of reflecting the solar energy. Since the insolation reflected has decreased, this may mean that the area of the ice sheets has decreased as well.
