- Earth is mostly covered by water, which accounts for about 70% of the planet’s surface.
- Lakes are small, freshwater bodies on land, filled by rivers, rain, springs, or runoff; their water eventually flows to seas via rivers and mixes with saltwater.
- Freshwater habitats like lakes may contain trout, frogs, perch, carp, and seaweed.
- Seas and oceans are large saltwater bodies, often very deep, and host animals such as whales, sharks, dolphins, stingrays, jellyfish, lobsters, and seaweed.
