Question

1. variations in the color of oceans are caused by

a. varying structures of water molecules.
b. no light penetrating any depth of the water
column.
c. solar plumes.
d. light interacting with other materials in the
water.

Explanation:

The color of the ocean is mainly due to the interaction of light with substances in the water. Water molecules have a relatively stable structure, so option a is incorrect. Light can penetrate a certain depth of the water column, so option b is wrong. Solar plumes are not the main cause of ocean color variation, so option c is incorrect. Light interacts with other materials (such as suspended particles, dissolved substances, and phytoplankton) in the water, which affects the absorption and scattering of light, thus causing color variations.

Answer:

d. light interacting with other materials in the water.
