Weather and Latitude

Does a low pressure or high pressure area bring rain and why?

• low pressure system where warm air is rising, cooling to form clouds often with precipitation.

• high pressure system where air is sinking, which indicates rain and storms.

• Neither

On an isobar map where would you likely see dry, clear skies?

• in a low pressure area, where clouds are able to form as there is not enough pressure to hold the clouds together.

• In a high pressure system, cool air is sinking toward the ground where it is compressed and warmed by Earth’s surface. The air is not able to rise and cool again to form clouds. Without clouds, there is no rain and hence the weather tends to be clear and dry.

• Neither

What causes the temperature differences at different latitudes?

• The equator is always closer to the sun so that is why it is warmer near the equator.

• As latitude increases so do the temperature.

• Sunlight is more intense near the equator and gets less intense the farther away from the equator you go.

• The equator is mostly water - there is more land north and south of the equator.

Which statements about what affects Earth’s temperatures are true.

• The angle at which light hits the Earth affects its intensity and temperature. The more the light is spread out, the less intense it is and lowers the temperature.

• The light from the sun hits the Earth most directly at the Earth’s poles, so the light is intense. This is where the highest temperatures are recorded.

• The temperature of the Earth varies by longitude. It is warmer east of the prime meridian.

Which statements about what affects Earth’s temperatures are true.

• The light intensity of the sun varies by latitude and corresponds to temperature. The more intense the light, the greater the temperature.

• The temperature of the Earth varies by longitude. It is warmer east of the prime meridian.

• The light from the sun hits the Earth most directly at the Earth’s poles, so the light is intense. This is where the highest temperatures are recorded.

What should we expect to happen at the surface of Earth, when there is a great difference in air pressure of two air masses over a smaller distance?

• When there are differences in air pressure and air temperature at the surface of the Earth, winds are formed but only when it is combined with cumulous cloud coverage. That is why winds are so difficult to predict.

• When there is a great difference in air pressure on Earth’s surface, we can expect to see the beginnings of a tornado form over a flat surface.

• When an air mass with high pressure meets an air mass with low pressure, they balance each other out and the air is calm.

• Where there is a great difference in air pressure of two air masses, we get strong winds. The greater the temperature difference the stronger the wind.

Why are seasons the opposite in the Northern Hemisphere and Southern Hemisphere?

• Seasons are opposite in the Northern and Southern Hemispheres because of Earth’s tilt as it revolves around the sun.

• There are months where the Northern Hemisphere is closest to the sun and there are months where the Southern Hemisphere is closest to the sun.

• Seasons have more to do with Earth’s surface features like mountains, availability of fresh water, and plant life than it has to do with where the Earth is in space.

• The magnetic poles are opposite and affect the air currents which affect the temperatures in the hemispheres.

Which of the following statements are correct? Select THREE correct answers.

• The shape of the Earth affects the angle at which sunlight strikes the Earth.

• Sunlight strikes the Earth most directly at the equator and the poles.

• The angle at which light hits the Earth affects its intensity. The more intense the light, the higher the temperature of that place.

• The farther away from the equator a place is, the less direct the sunlight

• The temperatures at the poles remain constant all year round.
