Answer:
I will explain.
Explanation:
Lava comes in two primary appearances: Pahoehoe and aa. The reason why they have two different types of appearances is because the older aa in the photo has weathered and the iron in it has oxided somewhat, giving it a reddish and chunky appearance. It also moves fast. Pahoehoe has a flow that is comparatively smooth or a "ropy" surface. Pahoehoe doesn't have the chunky appearance.
Porous, water-saturated layers of underground bedrock, sand, and gravel that can yield economically significant amounts of water are referred to as aquifers
Aquifers are subterranean formations of bedrock, sand, and gravel saturated with water that can economically produce significant amounts of water.
<h3>What is Real Bedrock?</h3>
Bedrock is solid rock that lies beneath surface soil or gravel. Sand and other layers on the seabed are also supported by bedrock. Consolidated rock, or bedrock, is solid and strongly bonded rock. Loose-grained unconsolidated rock is often found as subsoil.
<h3>Is bedrock really rock?</h3>
The bedrock that balances the earth's crust is solid rock. While the entire state is covered by bedrock, Maine is mostly covered by a layer of surface sediment, soil, and vegetation.

Discharge data from stream gauges are the most important data for studying the potential for flooding along a river for several decades into the future.
Move level (or water level) and streamflow (or discharge) are measured at locations called streamflow gaging stations. The stage is measured and recorded continuously by means of electronic devices.
Discharge, that's every now and then known as streamflow or water drift, is described because the charge at which an extent of water passes with the aid of a selected place. Discharge and gage peak are associated values.
It's far crucial due to its impact on water exceptional and on the dwelling organisms and habitats in the stream. large, unexpectedly flowing rivers can receive pollutants discharges and be little affected, while small streams have less capability to dilute and degrade wastes.
