Question

water moves by waves, tides and currents. water contains dissolved salts. whales, sharks, fish, and crabs live here. what am i?

Explanation:

• Estuaries: Partially enclosed coastal body where freshwater meets saltwater. Tides are prominent, but the description of water movement (waves, tides, currents) and the presence of whales, sharks (which are more typical in larger salt - water bodies) makes it less likely compared to marine.
• Marine: Covers oceans and seas. Water moves by waves, tides, and currents. Salty water (contains dissolved salts). Home to whales, sharks, fish, crabs.
• Rivers: Flowing freshwater bodies. No significant tides (except in some large river deltas, but not the main characteristic). Mainly fish (not typically whales and sharks in most rivers).
• Lakes: Standing freshwater (or in some cases, slightly saline in closed - basin lakes). No tides (except very minor seiche - like oscillations which are not the same as ocean tides). Limited to certain fish species (not whales and sharks in most lakes).

Answer:

B. Marine
