Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.
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
Answer: Thermal inversion
Explanation: Thermal inversion or change the position of the air layer, when the warmer layer of air is above the cold layer, which is usually not the case. It happens due to a change in the normal temperature gradient, i.e. when the gradient becomes inverted. Such thermal inversions can occur in oceanic areas with a lot of upwelling near the coasts. Thermal inversion also occurs when sun radiation is less than radiation from the earth, which is the case during the night. The significance of these inversions is great, especially for air quality in polluted environments such as urban. The strongest inversions are during the winter and can then be dangerous due to poor air quality, which is measured by the AQI (Air Quality Index). The higher the AQI index, the greater the risk of bad air, that is, the worse air.
B. The curtains on the windows of a bedroom.
The rest of the choices are not man-made which would not be infrastructure.
