It is called a river basin
High pressure and ocean currents causes dry summer season in San Francisco and abundant amount rainfall in Washington, DC.
High pressure cells combine with the different ocean currents off the coasts causes a summer dry season in San Francisco and abundant rainfall in Washington, DC because these pressure cell along with ocean currents carried out moist winds which turn into clouds lead to rainfall.
When moist winds blow inland, the high terrain of the Cascade Range forces the moist air to rise into the atmosphere, forming thick clouds and steady rainfall occurs in Washington, DC while on the other hand, San Francisco experience dry summer season and wet winter season due to presence near the water bodies so we can conclude that high pressure and ocean currents causes dry summer season in San Francisco and abundant amount rainfall in Washington, DC.

a. physical geography
b. human geography
Geography is divided into two main branches, physical geography, and human geography, and after that, they branch out much more and include the other geographical disciplines in them.
Physical geography is mainly concerned with the study of the natural characteristics of the Earth, both the ones on the surface and the once close to the surface.
Human geography is mainly focused on the study of the human race, the background, perceptions, interactions, organizing, human groups, effects on and from the environment etc.
One of the most destructive hazards associated with composite volcano eruptions are super-heated gases called pyroclastic flows.
<h3>What are pyroclastic flows?</h3>
The pyroclastic flows are harmful mixtures of warmed rocks and gases released during volcanic eruptions.
These pyroclastic flows are very harmful because they reach very high velocities (up 710 km per hour).
In conclusion, one of the most destructive hazards associated with composite volcano eruptions are super-heated gases called pyroclastic flows.
