According to geographical analysis, the volume of groundwater that flows over a given time per unit area through a body of rock or sediment is called the "<u>hydraulic head</u>."
This is because the hydraulic head is based upon the gradient of the water table, including the permeability of the rock or sediment and groundwater thickness.
Hydraulic head is calculated in the form of liquid surface elevation.
Hydraulic head is usually expressed in units of length.
Hence, in this case, it is concluded that the correct answer is "<u>hydraulic head</u>."

Answer:
"Organic" food distribution. Community markets were developed during the Mayan civilization to help get food to the people. Like today's farmers markets, the Mayans were able to connect with their growers and get the freshest foods available. It made for healthier diets and a strong market economy.

Answer:
At the start of the 20th century, temperatures were about 4.5°F cooler. The temperatures of the arctic are confronting the heatwave, very unusual for Arctic standards.
Explanation:
These changes in temperatures can be “grateful” to climate change. The climate changes will continue with raising the temperature in the Arctic. These climate changes are so usual at this moment on the Earth, that in a few decades people will be used to heat.
Volcanoes can be two broad types: stratovolcano and a shield volcano namely.
In volcanology, viscosity plays a crucial role. High viscous (extremely sticky) magma eruptions typically result in steep-sided volcanoes with 30-35° slopes. This is due to the fact that the viscous volcanic material doesn't flow very far once it is erupted; instead, it accumulates in layers to form a cone-shaped volcano called a stratovolcano. In contrast, shield volcanoes have mild slopes of less than 10° and produce more basalt fluid lavas during eruption. A shield volcano's eruption can cause the basalt to flow far from the vent, creating broad, gentle slopes.
