Question

1. what happens when more sunlight is absorbed by the earths surface due to melting ice?

a. global temperatures increase
b. ice caps expand
c. solar radiation decreases
d. greenhouse gases are reduced

Explanation:

• Option a: Melting ice reduces the Earth's albedo (reflectivity). When more sunlight is absorbed (instead of reflected) by the Earth's surface, it leads to more heat being trapped, causing global temperatures to increase.
• Option b: Melting ice causes ice caps to shrink, not expand.
• Option c: Solar radiation from the Sun is relatively constant; melting ice doesn't decrease it.
• Option d: Melting ice is a result of increased greenhouse gases (or other warming factors), not a cause of reducing greenhouse gases.

Answer:

a. Global temperatures increase
