The core has the largest density, being made of iron and nickel
The mantle has an intermediate density and the crust has the lowest density.
Answer:
Option (3)
Explanation:
The elasticity property of rock describes how a rock that is subjected to stress undergoes bending and again comes back to its original position. In nature, most of the rocks are non-elastic as they undergo deformation due to the stress acting on them. So the rocks are not always perfectly elastic.
According to Hooke's law, in case of a comparatively small deformations of an object, the displacement that occurs on the rocks or the deformation size that occurs is directly proportional to the amount of load that undergoes deformation.
Hence, the correct answer is option (3).
Sinkholes and caves may be right
The answer is; the theory of anthropogenic impact on the environment.
These anthropogenic activities that have an impact on the biodiversity, ecosystem and biophysical resources include, large-scale mono-cropping, deforestation, environmental pollution, and etcetera. These activities cause global warming and reduced biodiversity.
