Weather PowerPoint Review

What does weather describe?

• The future predictions of atmospheric conditions

• The present state of the atmosphere and the current conditions

• The historical climate patterns of a region

• The temperature of the core of the Earth

What are the factors that determine weather?

• Air pressure, wind, temperature, and the amount of moisture in the air

• Soil composition, sunlight, water currents, and plant life

• Ocean tides, phases of the moon, solar flares, and cloud shapes

• Types of rocks, altitude, animal behavior, and river flow

Weather is created by the interaction between:

• Air, water, and the sun

• Plants, animals, and minerals

• Mountains, valleys, and oceans

• The moon, stars, and Earth's magnetic field

At what altitude was the bottle sealed before it was crushed by the increase in atmospheric pressure?

• 9,000 feet

• 1,000 feet

• 14,000 feet

• Sea level

What caused the bottle to be crushed as it was brought down towards sea level?

• Decrease in atmospheric pressure

• Increase in atmospheric pressure

• Change in temperature

• Change in bottle material

Which altitudes are mentioned in the image where the atmospheric pressure affected the bottle?

• 14,000 feet and sea level

• 9,000 feet and 1,000 feet

• 14,000 feet and 9,000 feet

• 1,000 feet and sea level

What is humidity?

• The amount of heat in the air

• The amount of water vapor air can hold at a specific temperature

• The amount of carbon dioxide in the air

• The amount of oxygen in the air

What happens to the amount of water vapor that air can hold as the temperature increases?

• It decreases

• It stays the same

• It increases

• It fluctuates unpredictably

Why does the amount of water vapor that air can hold increase when the temperature increases?

• Because water molecules move slower and can join together more easily

• Because the air expands and can hold more water

• Because water molecules move faster and can't join together easily

• Because the air pressure decreases

What does relative humidity measure?

• The temperature of water vapor in the air

• The measure of the amount of water vapor in the air compared to the total amount it has room for on a particular day

• The amount of precipitation in the air

• The speed of water vapor movement in the air
