answer
A model in science is ( correct answers ) a simpler system that is
analogous to the real system.
A team member notices that the winds blowing persistently from the
west over tend
mountain a to produce rain on the western side of the mountain but
much
on theless
eastern
rain side. ( correct answers )
observation
Based on knowing that temperatures tend to decrease with increasing
height, the
proposes that
team
maybe the moist air is being cooled when the wind from
west tothe
forces east
air upward. ( correct answers ) formulating a
hypothesis
The team tests this idea in the laboratory by measuring the
temperature
cylinder with inside
a movable
a piston so they can change the pressure of the
air, simulating
moving to the air to greater height. ( correct answers )
using a model
Based on extensive research results on prevailing winds, and how air cools
when it is
uplifted by winds over a mountain, the team develops a widely applicable
explanation
of rainfall and snowfall around mountains. ( correct answers )
constructing a
scientific
explanation
