Q. Study of the nature of the old sedimentary rocks gives an indication about the
1. Age of the earth
2. Past environmental conditions
3. Old civilizations.
4. Direction of plate movements.
1. Age of the earth
2. Past environmental conditions
3. Old civilizations.
4. Direction of plate movements.
✅ Correct Answer: (D)
Only 2
Explanation:
Study of old sedimentary rocks mainly provides information about past environmental conditions like climate, sea levels, and life forms.
- They do not directly give the age of the Earth (which is determined by other methods like radiometric dating).
- They don’t provide information about old civilizations (which are studied through archaeology).
- Direction of plate movements is studied through tectonics and rock formations, but not solely from sedimentary rocks.
So, the study indicates mainly past environmental conditions — option (D).
