<span>Nasal conchae and meatuses Nasal conchae, also known as nasal turbinates, are curved shelves of spongy bones forming in the walls of human nose. The nasal conchae function is to regulate the airflow through the nasal passages to provide rapid warming and humidifies air as it passes to the lungs. The nasal conchae divides the nasal cavity into ducts or meatuses, this are <span>the passages in the nasal cavity formed by the projections of the nasal conchae.</span></span>
The correct answer is - B) convection currents in the mantle.
There's multiple tectonic plates on the surface on the planet, around 17 from what is known so far, but as the scientific methods are developing there might be few more discovered in the years to come.
These plates are all moving, only few cm per year, but on the long term it influences and changes everything on the surface on the Earth.
The movement of the plates is the result of the convection currents in the mantle layer beneath. These convection currents are essentially the combination of the high temperatures, high pressures, and viscous metals, and they managed to break up the crust on the surface, and with its push force, they are slowly moving the plates.
With the movement of the plates and their collisions and moving away, lots of earthquakes and volcanoes are appearing all over the plate boundaries.
The answer is volcanic mountains

Answer:
B. Death Valley, CA
Explanation:
Here are the elevations of each location:
Key West, Florida 18 feet
Death Valley, California -282.2 feet
Seattle, Washington 175 feet
Corpus Christi, Texas 7 feet
Because Death Valley sits at -282.2 feet below sea level, the lowest elevation, <u>B is the answer</u>.
Tip: Without knowing the exact elevations of each location, we could assume that a <em>valley</em> would be lowest.
