The weather event known as La Niña results in which of the following?
Drought in Western South America
Dry season in Southern Africa
Hurricanes in the Gulf of Mexico
Warming of the Indian Ocean
Drastic rise in sea level on the coast of Japan
La Niña usually results in a warming of the water along the equator, which changes weather patterns across the world. South America experiences a severe drought, while precipitation is pushed South towards Africa.
The Smokey Mountains are known for the fog that hovers over the mountains. Fog is created when water vapor condenses and suspends. What measurement of atmosphere moisture is used to predict fog?
Dew point
Precipitation
Convection currents
Climate
The correct response is dew point. This is a measurement of the temperature at which water vapor will condense. If the dew point temperature and air temperature are within a few degrees of each other, then fog is likely.
It is difficult to predict the meteorological conditions of our world on a day to day basic. Meteorologists sometimes miss a snowstorm or underestimate a powerful rainstorm on any given day. However, we do understand the general trends in temperature and rainfall for any given year. The trends in temperature and rainfall for a given region are referred to as __________.
climate
weather
season
precipitation
The correct response is climate. The word climate refers to constant weather patterns over many years. The word weather refers to the day-to-day conditions.
Which of the following does not impact an area's climate?
The population dynamics of the keystone species
The Earth's rotation
Patterns of air and water movement
Gases in the atmosphere
The Earth's surface features
Climate may impact the population dynamics of a keystone species, but not the other way around.
