Question 11: light rain showers followed by hot temperatures and humid conditions

Question 12: a 7-day weather forecast

Question 13: short-term forecasting

Question 14: precipitation

Question 15: low pressure

Answer 3

Question 1: The evidence that radiation from the sun heats planet Earth can be seen in the statement "The ocean temperatures warm when there is more sunlight in summer." This statement shows that the increase in sunlight during the summer leads to higher ocean temperatures.

Question 2: The statement that shows conduction of heat is "Jillian burns her fingers when removing a light bulb from a lamp without turning it off first." Conduction of heat occurs when heat is transferred through direct contact, as in this scenario when Jillian's fingers come in contact with the hot light bulb.

Question 3: The ultraviolet ray that is most harmful to living things is UVB. UVB rays are the shorter and more energetic of the two main types of ultraviolet radiation from the sun. They can cause damage to the DNA in skin cells and are most responsible for sunburns and skin cancer.

Question 4: Water changes its state through the process of evaporation. Evaporation occurs when heat is applied to water, causing the water molecules to gain enough energy to break their bonds and convert into vapor.

Question 5: The difference between sleet and hail is that sleet is a form of precipitation, while hail is not. Sleet occurs when raindrops freeze into ice pellets before reaching the ground, while hail is formed in thunderstorms when updrafts carry raindrops upward and freeze them into layered ice pellets.

Question 6: It is more likely to feel sticky in summer than in winter because warm air can always hold more water vapor than cool air. Relative humidity, which is the amount of moisture in the air compared to its maximum capacity, tends to be higher in summer when warm air can hold more water vapor.

Question 7: Relative humidity is defined as the amount of water vapor in the air compared to the amount of water vapor at saturation. It is not compared to the dew point temperature, the air temperature, or the amount of water vapor at 0ºC.

Question 8: On a sunny day, a high-pressure system is expected. High-pressure systems are associated with clear weather and sinking air, which leads to sunny conditions.

Question 9: The difference between high-pressure and low-pressure systems is that in high-pressure systems, air converges on one area, while in low-pressure systems, surface air moves outward. High-pressure systems bring clear weather, while low-pressure systems are associated with cloud formation and precipitation.

Question 10: An air mass that would form over a cold, dry region of land is a continental polar air mass. Continental polar air masses originate over cold land areas and are generally dry and cold.

Question 11: If a warm front is moving into the region from the southwest, the family will most likely experience cloudy skies and rain showers followed by cold temperatures and dry conditions. Warm fronts bring gentle, steady precipitation and are followed by cooler temperatures.

Question 12: In order to get the most accurate prediction for their hiking trip, the family should check a 3-day weather forecast. Shorter-term weather forecasts are generally more accurate than longer-term forecasts.

Question 13: To make their decision on whether to go to the zoo on Saturday or Sunday, the family should check short-term forecasting. Short-term forecasts provide the most accurate and up-to-date information for the specific days the family is planning their trip.

Question 14: The process where tiny condensed water droplets combine and fall back to the earth is called precipitation. Precipitation includes various forms of water falling from the atmosphere, such as rain, snow, sleet, and hail.

Question 15: The weather is cooler at higher altitudes because of low pressure. As altitude increases, the air pressure decreases, and air molecules become more spread out. This leads to cooler temperatures due to the decrease in air molecules and energy.
