Use the table to answer the question. Day Observations 1 sunny and warm 2 cloudy and rainy 3 drop in temperature 4 clear skies and cold temperatures A student tracks the daily weather. The student’s observations are logged in the table. Which factor in the atmosphere best explains the student’s observations? (1 point) Responses A warm front moved into the area. A warm front moved into the area. A cold front moved into the area. A cold front moved into the area. A warm air mass replaced a cold air mass. A warm air mass replaced a cold air mass. High levels of moisture are contained within an air mass. High levels of moisture are contained within an air mass.

The student's observations of a drop in temperature, followed by clear skies and cold temperatures, best explain that a cold front moved into the area.

A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) Responses There is no chance of precipitation in the forecast. There is no chance of precipitation in the forecast. Warm temperatures will replace cold temperatures. Warm temperatures will replace cold temperatures. A significant drop in temperature will occur across the area. A significant drop in temperature will occur across the area. Humidity levels will rise. Humidity levels will rise.

Based on the weather map showing a blue line with triangles approaching a red line with semicircles, the most valid weather prediction is that a significant drop in temperature will occur across the area.

Which factor in the atmosphere is most responsible for changes in an area’s temperatures and humidity levels?(1 point) Responses different types of cloud formations different types of cloud formations amount of precipitation amount of precipitation movement of large air masses movement of large air masses density of air

The movement of large air masses is most responsible for changes in an area's temperatures and humidity levels.

just give me the answer

The answer is: movement of large air masses.

Use the weather forecast from a meteorologist to answer the question. “Temperatures will plummet late Thursday night through Saturday. All areas across the eastern region of the state are anticipated to be below freezing by Friday morning and again on Saturday morning. Heavy amounts of snow are possible late Thursday into Friday. High winds can also be expected across the area.” Which news headline best accounts for this change in weather? (1 point) Responses “A Warm Air Mass Forms over the Region” “A Warm Air Mass Forms over the Region” “A Strong Cold Front Threatens the Region” “A Strong Cold Front Threatens the Region” “A Warm Front Blankets the Region” “A Warm Front Blankets the Region” “A Cold Air Mass Exits the Region”

The news headline that best accounts for this change in weather is "A Strong Cold Front Threatens the Region."

Which condition would most likely require the National Weather Service to issue a severe thunderstorm warning?(1 point) Responses an air mass developing over a large body of water an air mass developing over a large body of water a front moving out of an area a front moving out of an area a large amount of moisture in the air condensing to form clouds a large amount of moisture in the air condensing to form clouds a meeting of two air masses with major differences in temperature and moisture
