Sample Questions
Which of the following are components of the hydrological cycle?
Show answer
Evaporation, Condensation, Precipitation, Evapotranspiration
The hydrological cycle includes evaporation (water turning to vapor), condensation (vapor forming clouds), precipitation (rain/snow), and evapotranspiration (water release by plants). Photosynthesis is not part of the water cycle.
Which factors affect the temperature of sea water?
Show answer
Angular height of sun, Ocean currents, Winds, Geographical location
Sea water temperature is affected by angular height of sun (latitude), ocean currents (warm/cold), winds (continental/oceanic), and geographical location (landlocked vs open seas). Moon phases affect tides, not temperature.
Ocean waves are primarily created by which factor?
Show answer
Winds
Sea waves are primarily created by winds. While earthquakes, gravitational forces, and other factors can also create waves, wind is the main factor causing the regular wave motion we observe on ocean surfaces.
What causes tides and ebbs in oceans?
Show answer
Gravitational forces of sun and moon
Tides and ebbs are caused by the gravitational forces of the sun and moon. These celestial bodies pull the ocean water, causing it to rise (tide) and fall (ebb) in a regular pattern.
