1-3 Question and answers correctly
solved
As seen in a US weather map, the H (or High) and L (or Low) symbols
indicate regions where surface air pressures are high or low, respectively,
compared to surrounding areas. An H is plotted where the air pressure is
highest and an L is plotted where the air pressure is lowest. Proceeding
outward and away from the center of a high pressure system, the air
pressure......... - correct answer ✔Falls
Fronts are boundaries between air masses that usually contrast in
temperature. Above the Earth's surface, fronts slope upward and over the
__________air. - correct answer ✔colder
Weather radar emits pulses of ______ energy to detect precipitation. - correct
answer ✔microwave
What advantages does an infrared satellite image offer over a visible satellite
image for monitoring the state of the atmosphere? - correct answer
✔Infrared satellite sensors detect infrared radiation that is continually emitted
to space by the Earth-atmosphere system. Hence, infrared images can be
obtained 24 hours a day. Visible satellite sensors detect sunlight reflected by
the Earth-atmosphere system. Hence, visible images are possible only during
daylight hours; where as the visible ones are only useful during the day
__________ is used to describe the wright of the overlying air. - correct
answer ✔Pressure
, __________ pressure systems are usually accompanied by fair weather and
______ pressure systems are usually accompanied by stormy weather. -
correct answer ✔High..........Low
Viewed from above in the northern hemisphere, surface winds in a low
pressure system blow............. - correct answer ✔Counter clockwise and
inward
Weather systems in the middle latitudes of the Earth generally move in the
direction towards the............. - correct answer ✔East
An air mass is a huge volume of air that is relatively uniform horizontally
in............. - correct answer ✔temperature & humidity
The temperature and moisture characteristics of an air mass depend
on........... - correct answer ✔the properties of the surface over which the air
resides and travels.
_______________ fronts are associated with cloudiness and precipitations
over a broad geographical area. - correct answer ✔Warm
Cloud appear on __________ satellite images. - correct answer ✔Visible,
Infrared & Water Vapor
The scientific method is a systematic form of inquiry involving ............ - correct
answer ✔observation, interpretation, reasoning and speculation.
What is the significance of the stratospheric ozone for life on earth? - correct
answer ✔This ozone prevents many of the high energy ultraviolet solar
radiations from contacting the earth's surface.
