“How do we classify peatlands that still produce peat?”
Peatlands may no longer produce peat if they are burned or drained. Peatlands that are still waterlogged and produce peat are called Mires.

“What causes peatlands to stop producing peat?”
Peatlands produce peat from their water-saturated conditions. If a peatland is drained or burned, these conditions can fall away. This is When Peatlands Stop Producing Peat.

“How do we classify wetlands that produce peat?”
Peat is a buildup of dead leaves in high-moisture, low-oxygen conditions. Peatlands are wetlands that produce peat. Peatlands are the highest land-based carbon storage source on Earth.

“What types of groundwater-dependent wetlands accumulate peat?”
Swamps come in all different types. Some wetlands are dependent on high groundwater tables that accumulate peat. These so-called Fens typically have mineral-rich conditions that support large plant life. Fens typically have higher ph level than bogs.

“What types of rain-dependent wetlands accumulate peat?”
There are a myriad of different types of wetlands. Wetlands that rely on precipitation and accumulate peat are called Bogs. Bogs have low oxygen and high acidity levels. Because bogs are typically fed by precipitation instead of nutrient-laden groundwater, plants in bogs may have adaptations to survive in these harsh conditions, such as carnivory.

“What happens when large layers of dead vegetation pile up in a wetland?”
Vegetation grows and dies. Dead plant material in a waterlogged environment may decay slowly due to a lack of available oxygen. More dead material will pile up over time, leading to the creation of Peat. Peat is an organic material that stores carbon from the original plant material, retains and filters water, and supports ecosystems.

“Why are there underwater forests?”
Forests form from a dense community of trees. Climate change and land subsidence can cause sea-level rise to submerge forests. Sediment and mud can cover the tree trunks, sealing them off from oxygen and preserving these spaces as Submerged Forests. Submerged forests are a relic of coastal geology and ecosystem status from previous eras. Many more submerged forests will form if humans do not stop climate change.

“How can deserts form along the coast?”
When people discuss deserts, it’s easy to imagine an endless inland expanse of sand. But deserts can form over coasts too. Cold currents in the tropics will cause cold air to move along the western coastlines of continents. This cold air doesn’t rise upward to form clouds, and instead stays in a stable fog layer. This low cloud formation limits rainfall along the coasts, forming Coastal Deserts. Coastal deserts are cooler and more stable climates than other deserts, and the fog moisture creates fertile conditions for unique organism evolution. Famous coastal deserts include the Namib Desert (pictured) in southern Africa and the Atacama Desert in Chile.

“How can the sea advance over land?”
It’s easy to assume coastlines are permanently static. However, the sea can advance over land either through sea level rise, land subsidence, or both. This process is known as Marine Transgression. Jakarta, the largest city in Indonesia, is a prime example of this.
