“What happens when soils are hypersaturated with water?”

Soils can be saturated by water from time to time. When they become hypersaturated by water, they can become anaerobic (oxygen-deprived) Hydric Soils that can support swamplands.

“How can tectonic movements create estuaries?”

Estuaries are magnificent forms of nature. One of the most fascinating ways estuaries are formed is when tectonic movement causes a piece of land to sink and for surrounding water to fill it. This forms a Tectonic Estuary. The San Francisco Bay is an example of a tidal estuary.

“How can barrier islands create special estuaries?”

Barrier islands protect mainlands from harsh storms. Sometimes their backside also forms an estuary with a nearby river. These Bar-Built Estuaries typically have low water volume flows with the surrounding ocean, and can even temporarily turn into lagoons. The Salmon River in Oregon is an example of a bar-built estuary.

“What is the equivalent of roots for ocean algae organisms like seaweed?”

Ocean algae organisms like seaweed are attached to ocean ground. But what attaches them to that ground? Well, it comes in the form of something called a Holdfast that functions much like roots.

“Are there creeks that only flow during rain?”

People typically think that water in creeks flows throughout the entire year. However, some creeks only flow during precipitation events. These Ephemeral Creeks are more common in arid and semi-arid environments.

“Can plants have aboveground roots?”

Plant roots are associated with being buried in the ground. But they can also extend into the air above ground. Plants with Aerial Roots can absorb moisture and nutrients from the air.

“Why do plants have roots?”

Roots are one of the most recognizable features of a plant. But why do they have them? Well, it’s because roots help the plant absorb water and nutrients while anchoring it to the soil. This is Why Plants Have Roots.

“What are plants that have adapted to aquatic life?”

Plants can be found all over the world. Aquatic Plants are plant species that are specifically adapted to aquatic ecosystems. These typically come with a few adaptations that make their survival feasible.
