Answer:
Option (1), (2) and (3)
Explanation:
The subduction zones are created when a denser oceanic plate subducts under a lighter continental or oceanic plate. It forms at the convergent plate boundary. The point above this subduction zone where the depression forms is known as the oceanic trenches. This trenches extends up to a great depth. The subducting plates undergoes partial melting as a result of which the plate melts and the magma rises up towards the over-riding plate forming volcanoes or chain of volcano. This type of plate boundary generates deep focus earthquakes.
Thus, the correct answer are option (1), (2) and (3).
Answer and Explanation:
We can consider the city and the forest as two terrestrial ecosystems. In these two ecosystems, we can consider humans and plants as biotic components. Since the entire biological community is considered to be biotic environments, that is, it lives from a place. As abiotic components we can consider sunlight and soil. This is because the abiotic components are everything that has no life.
Following the same reasoning, we can consider fish and water as the biotic and abiotic component of the aquatic ecosystem.
Scientists need to gather information that is based on direct observation rather than opinion or feelings.
