The mountain ranges and rivers in Southeast Asia have made a stripe like relief in the mainland of this region. The mountain ranges are in a north-south direction and separate the region into few big elongated valleys, and the 5 big rivers also are moving from the north towards the south (southeast, southwest as well), and are running in between the mountain ranges and cut through the valleys.
I believe B. the material is cooler and denser would be correct.
The colder something is, the more density it has. Earth's core is too hot to be very dense, so that's why I would go with B.
Answer:
C. the addition of new lithospheric mantle as a result of cooling
Explanation:
- The oceanic lithosphere is a part of the asthenosphere and the upper mantle and its thickness depend on the distance away for the mid-oceanic ridges.
- This is evident from the studies of the seafloor spreading and the cooling of the plates and rocks masses. As the hot magma upwells and then cools at a certain degree and the cooled plates move away from the center.
Explanation:
There are several effects of tropical rainforest deforestation on the local environment.
Deforestation is the removal of the land cover usually shrubs and vegetation. This often leads to;
- Loss of habitat for arboreal organisms that depends on trees for their dwelling.
- Increase likelihood for desertification of an area.
- exposure of the land surface to erosion, and this leads to removal of the fertile soil top layer.
- loss of soil fertility and productivity for the ecosystem.
