Answer:
The best place to look for a sandy beach in a meandering river for swimming is typically on the inside bend of the meander where a point bar has formed. Point bars are depositional features that form on the inside bend of a meander where the water slows down and sediment is deposited, often creating a shallow area with a sandy beach. In contrast, the outside bend of the meander typically has a faster flow and deeper water, making it less likely to have a sandy beach. A cut bank, which is an erosional feature on the outside bend of the meander, is also less likely to have a sandy beach for swimming.
in coastal communities, high rates of fresh groundwater withdrawal can raise the boundary between fresh and underlying saltwater aquifers and contaminate water supplies with salt. this process is called
The process described, in which high rates of fresh groundwater withdrawal lead to the intrusion of saltwater and contamination of water supplies, is called saltwater intrusion.
Saltwater intrusion occurs when the pumping of freshwater from aquifers exceeds the recharge rate, causing a reduction in groundwater levels. As the freshwater is depleted, saltwater from surrounding saltwater aquifers or the nearby ocean infiltrates into the freshwater aquifers.
This intrusion of saltwater can lead to the contamination of previously fresh groundwater sources with high levels of salt, making the water unsuitable for drinking or irrigation.
Coastal communities, especially those located in low-lying areas, are particularly susceptible to saltwater intrusion due to their proximity to the ocean and the presence of underlying saltwater aquifers.

what is name of the medium used that is a lava rock or clay pellet?
The medium that is commonly used in gardening and hydroponic systems, and is known for its high porosity and ability to retain moisture, is called "growing media".
This includes various types of substrates, such as soil, coconut coir, peat moss, perlite, vermiculite, and others. In particular, lava rock and clay pellets are two types of growing media that have gained popularity among gardeners and hydroponic enthusiasts. Lava rock is a porous and lightweight volcanic rock that provides excellent drainage and aeration for plant roots. Clay pellets, on the other hand, are made of fired clay and offer good moisture retention and stability. Both types of media are suitable for a wide range of plants and can be used alone or mixed with other substrates.
