For many of the early surveys that explored the western parts of North America, an aneroid barometer was an integral piece of scientific equipment. What was the principal use of the barometer on these surveys? Aneroid barometers were used to determine elevations along the survey route. Aneroid barometers were used to determine the shortest route to water. Aneroid barometers were used to determine longitude and latitude. Aneroid barometers were used to predict the weather during the trip. Aneroid barometers were used to determine distance traveled each day.

A __________ is another name for winds that blow in an onshore direction during the day. convection cell valley breeze land breeze chinook sea breeze

Which of the following is a true statement regarding land breeze? Air over the land is moving upward, while air over the sea is moving downward. It blows in an onshore direction. It occurs during the day. Air moves from a high-pressure zone at low altitude above the land toward a low-pressure area at low altitude over the sea. It is caused by the land being warmer than the sea.

A valley breeze is defined by __________. an air mass that moves downslope and increases in volume rising warm air that triggers cloud formation at high elevations cool air sinking and warm air rising at night rising cool air and cloud formation at high elevations cool air rising and displacing warm air downward

A __________ occurs at _____, when cold air travels downslope and warm air rises. valley breeze, night chinook, day mountain breeze, night land breeze, night mountain breeze, day

Which of the following distinguish a chinook from other types of breezes? Chinooks increase in volume and warm up while moving downslope. Chinooks trigger cloud formation and condensation in mountainous regions. Chinook winds decrease in both temperature and volume moving downslope. Chinooks travel in convection cells that blow in an onshore direction. Chinooks carry warm, moist air that causes frequent precipitation.
