Solution
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.
