Which of the following statements is correct? The earth is cooled by terrestrial radiation. The earth's temperature is not affected by solar radiation. The earth is heated by terrestrial radiation. The earth's temperature is not affected by terrestrial radiation.

The earth is cooled by terrestrial radiation.

Why does air have weight? Because everything has weight The force of gravity acts on the air molecules' mass The pressure of the air molecules colliding with each other gives them weight Air fills its entire volume, producing weight

The pressure of the air molecules colliding with each other gives them weight

Which statement accurately describes why air pressure decreases as altitude increases? As you increase altitude the temperature difference between the layers of the atmosphere causes extreme winds and the air pressure in turn decreases. As you increase altitude, the air particles move around much more quickly because they have to travel further distances which decreases their pressure. As you increase altitude the temperature is increased and as you heat particles they spread further apart decreasing their pressure. As you increase altitude, Earth's gravity is not acting as greatly as when closer to Earth's surface so the weight of air molecules decrease, which also in turn decreases air pressure.

Low air pressure usually means bad weather. This is because _____. warm air rises and condenses, usually forming clouds and precipitation cold air rises, forming clouds and precipitation high pressure brings in cold air to the low pressure area cool air is usually full of moisture, which makes it humid and rainy

warm air rises and condenses, usually forming clouds and precipitation

Water vapor holds in heat and distributes it during the _____. nitrogen cycle carbon-oxygen cycle water cycle phosphorus cycle

water cycle
