Define insolation

• Insolation is the measure of wind speed in a given area.
• Insolation is the incoming radiation, also the earth's main source of energy

• Insolation refers to the total amount of rainfall in a region.
• Insolation is the process of converting solar energy into electricity.

Explain how solar radiation and the properties of air cause changes around the Earth

• Solar radiation is constant and does not change throughout the day.
• It causes the air to circulate in the atmosphere, bringing both warm and cold airs to different regions.

• Air properties have no impact on weather patterns.
• Solar radiation only affects the oceans, not the atmosphere.

Answer explanation

Also moves water vapor around the planet, which causes some regions to have more precipitation than others.

Identify 3 primary causes of the uneven warming patterns of Earth

• Distance from the sun
• Seasonal changes in weather
• 1. Angle of sunlight at different latitudes 2. Variations in land and water distribution 3. Some areas reflect more solar energy than others

• Presence of greenhouse gases

Why does the length of the Sun's rays cause unequal heating of Earth's surface?

• The Sun's rays are always parallel, causing uniform heating.
• The curvature of the Earth causes the Sun's rays to hit at varying angles, leading to unequal heating.
• The Earth's rotation prevents any heating from occurring.
• The atmosphere absorbs all of the Sun's rays equally.

Describe how the amount of surface area leads to uneven warming of Earth

• The uneven distribution of surface area on Earth leads to different rates of heat absorption and radiation, causing uneven warming.
• All areas of Earth warm at the same rate regardless of surface area.
• The amount of surface area only affects ocean temperatures, not land.
• Surface area has no effect on temperature variations.

Define albedo

• Albedo is the percentage of reflectivity of a surface.

• Albedo is the speed at which light travels through a medium.
• Albedo refers to the density of a material.
• Albedo is the measure of temperature of a surface.

Define high albedo

• High albedo is the ability of a surface to absorb all incoming sunlight.
• High albedo refers to a surface that emits more heat than it receives.
• High albedo is the property of a surface that reflects a large percentage of incoming sunlight.
• High albedo is the characteristic of a surface that reflects only a small percentage of sunlight.

Define low albedo

• Low albedo is a measure of a surface that absorbs all sunlight.
• Low albedo is a measure of a surface that reflects less sunlight.
• Low albedo indicates a surface that reflects more sunlight than average.
• Low albedo refers to a surface that emits heat instead of reflecting light.

What causes Earth's seasons?

• The distance from the sun changes throughout the year.
• Earth's rotation speed affects the seasons.
• The tilt of Earth's axis causes the seasons.
• The amount of sunlight varies due to cloud cover.

How do the seasons differ between Northern and Southern Hemispheres?

• The Northern Hemisphere has summer when the Southern Hemisphere has winter, and vice versa.
• Both hemispheres experience the same seasons simultaneously.
• The seasons are reversed only in tropical regions.
• The Northern Hemisphere has winter when the Southern Hemisphere has summer.
