Which directly contribute to the sea level rise

Question

Reflected energy and melting sea ice
expansion and melting of land ice
reflected energy and carbon dioxide
carbon dioxide and water vapor

Answer 1

The factors that directly contribute to sea level rise are primarily:

1. Expansion of seawater as it warms (thermal expansion) due to increased global temperatures.
2. Melting of land ice, which includes glaciers and ice sheets (such as those in Greenland and Antarctica) that contribute freshwater to the oceans.

Given the options you've listed, the correct choice is:

Expansion and melting of land ice.

While melting sea ice (like that in the Arctic) does not contribute directly to sea level rise because it is already floating, the melting of land ice and the thermal expansion of seawater are the main contributors. The other options related to reflected energy and gases like carbon dioxide do not directly cause sea level rise. However, they may influence climate change, which subsequently affects sea level rise.
