Which statement would correctly support the type of front and weather occurring along the front in the picture below?

• Warm Front-Warm air quickly rising over cold air, producing thunderstorms

• Cold Front- Cold dry air pushing the warm moist air up quickly, producing Thunderstorms and possible tornado

• Stationary Front- Both cold and warm air pushing from both sides causing the front to not move, producing showers

• Cold Front- Warm moist air is gently gliding over the cold air, producing thunderstorms, hail, and possible tornado

Look at the map below, which forecast is supported by the information shown?

• The lines marked are called isotherms and they show the temperature. Since the numbers increase across the map from West to East, it would mean that the temperature would increase in the next couple of days in the Eastern United States.

• The lines represent wind speeds which can be used to determine the direction air masses are moving. Since the numbers decrease on the right side of the map there should be less wind on the east coast of the United States.

• The lines represent boundaries of air masses and can be used to locate weather fronts. Since the number 30 represents a cold front and the numbers to the west of it are smaller, this would mean a warm front is moving to the Eastern United States.

• The lines represent isobars which measure air pressure. High numbers represent high pressure areas while low numbers represent low pressure areas. Since weather moves west to east the isobars show a low pressure area moving towards the Eastern United States which will bring cloudy weather and possible rain

Which statement below correctly explains how a hurricane is created?

• Warm humid air rises. This creates a low pressure area over the ocean. Nearby cooler air spirals towards the center. Warm humid air continues to fuel the storm. The lower the air pressure is at the center, the stronger the winds blow, and the hurricane grows larger.

• Cool humid air rises. This creates a high pressure area over the ocean. Warmer air is pushed away from the center. This continues to fuel the storm. The Higher the air pressure is at the center, the stronger the winds blow, and the hurricane grows larger.

• Warm humid air sinks. This creates a high pressure area over the ocean. Warmer air is pushed away from the center. This continues to fuel the storm. The Higher the air pressure is at the center, the stronger the winds blow, and the hurricane grows larger.

• Cooler humid air sinks. This creates a high pressure area over the ocean. Nearby cooler air spirals away the center. Cool air continues to fuel the storm. The higher the air pressure is at the center, the stronger the winds blow, and the hurricane grows larger.
