Which of the following is a correct description of a subdivision of geography? 1)hydrology studies the soils of the earth 2)oceanography studies the physical features, chemical properties, and biological characteristics of the oceans. 3)pe dology (or soil science) studies mountains, river valleys, volcanoes, and other land forms on the surface of the earth. 4)meteorology studies the climates of the world.

2) is correct. Oceanography studies the physical features, chemical properties, and biological characteristics of the oceans.

1) Hydrology studies the movement of water through the planet, not the soils of the earth.

3) Pe dology ( won't let me post this word) does mean "soil science", but it studies the soil itself, and its various properties, rather than land forms. 

4)Meteorology, more specifically, studies the atmosphere. Climate and . weather are major factors, however  

Ithink the answer is d.
