Question

Assertion (A): Remote Sensing satellite is a good tool and a useful source for gathering environmental information of earth’s atmosphere, ocean and land.

Reason (R): It can provide detailed information on landforms, air quality, rate of deforestation and cyclone.

विकल्प

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is true and (R) is false.

• (A) is false and (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Remote‑sensing satellites provide wide‑area, repeatable digital measurements across multiple spectral bands, enabling mapping of landforms, monitoring vegetation loss/deforestation, estimating air‑quality parameters and detecting/track­ing cyclones, which directly explains why they are a good tool for gathering environmental information.
