Question

what is the main purpose of ice drilling?
a. to collect soil samples
b. to observe polar wildlife
c. to track marine migration
d. to analyze past climate conditions
which of the following primarily focuses on studying earth’s frozen areas?
a. astronomy
b. marine biology
c. atmospheric studies
d. cryosphere research

Explanation:

First Question (What is the main purpose of ice drilling?)

• Option a: Ice drilling is not for soil samples (soil is different from ice cores).
• Option b: Ice drilling doesn’t directly observe polar wildlife.
• Option c: Tracking marine migration is unrelated to ice drilling.
• Option d: Ice cores preserve past climate data (like gas bubbles, isotopes), so analyzing past climate is the main purpose.

• Option a: Astronomy studies space, not Earth’s frozen areas.
• Option b: Marine biology focuses on marine life, not frozen areas.
• Option c: Atmospheric studies focus on air, not frozen regions.
• Option d: Cryosphere research specifically studies Earth’s frozen parts (ice, snow, permafrost, etc.).

Answer:

d. To analyze past climate conditions
