What angle is Earth's axis tilted at?
23.5 degrees
If Earth's axis were vertically aligned, what would happen?
Everywhere on Earth would have 12 hours of daylight
What are the dividing lines between the tropical and subtropical zones on Earth?
Tropics of Cancer and Capricorn
What causes the Northern and Southern Hemispheres to experience opposite seasons?
Unequal distribution of insolation due to Earth's tilt
What is the role of Earth's revolution around the sun?
Leading to seasonal variations
How do poles differ in terms of daylight during their respective summers?
South Pole is mostly in darkness
What happens to insolation and heating during summer?
More insolation, increased heating
How does the angle of solar radiation affect heating on Earth?
Higher angle of solar radiation leads to increased heating.
What happens to temperature as latitude changes northwards or southwards?
Temperature decreases.
What is the relationship between insolation and latitude?
Insolation is greatest at the Equator.
At which latitudinal point does the Earth receive the most direct solar radiation?
0° (Equator)
What is the primary cause for differences in heat spread between the Equator and the poles?
Angle of solar radiation
How do different latitudinal points on Earth differ in terms of insolation?
Latitudinal points closer to the poles receive more insolation.
What defines Earth's bands or zones of heat primarily?
Latitude
Which latitudinal point experiences the lowest temperature?
-90° S
How does insolation change as latitude moves northwards or southwards?
Insolation decreases as latitude moves northwards or southwards.
In what direction does temperature tend to fluctuate as distance from the Equator increases?
Temperature tends to decrease.
What would happen if Earth's axis were aligned vertically?
Everywhere on Earth's surface would have 12 hours of daylight and 12 hours of night-time.
How does the tilted axis of the Earth impact day and night lengths?
It results in unequal day and night lengths over different parts of the Earth.
What is the significance of Earth's revolution around the sun?
It causes variations in day length and sunlight intensity.
Which latitudinal point exhibits extreme seasonal differences?
North Pole
What happens during summer due to the tilted axis of the Earth?
More insolation and increased heating
How do the Northern and Southern Hemispheres experience seasons?
They experience opposite seasons at the same time.
What is the role of Earth's orbit around the sun?
To cause variations in daylight duration throughout the year.
How do different parts of the planet experience seasons during Earth's orbit?
Each part experiences unique seasons based on its latitude.
What is one consequence of Earth's axis being vertically aligned?
Constant day length throughout the year.
Why do poles exhibit extreme seasonal differences?
As a result of receiving varying angles of sunlight throughout the year.
What effect does the unequal distribution of insolation by Earth's tilted axis have on ocean currents?
It leads to different temperature changes in ocean currents.
How do warm ocean currents contribute to the temperature distribution on Earth?
They transfer heat from the poles to the equator.
In what direction do cold ocean currents generally flow?
Toward the poles
How do ocean currents help maintain a balance of energy on Earth's surface?
By transferring heat from polar to temperate zones
What role does ocean current play in facilitating the transfer of incoming heat energy?
Ocean currents move warm and cold water, aiding in heat transfer.
How do cold ocean currents differ from warm ocean currents?
Cold currents move towards the equator, while warm ones move towards the poles.

What is the primary impact of warmer water near the equator and cooler water near the poles?
To support the transfer of heat energy through ocean currents
How do warm ocean currents contribute to maintaining global temperature equilibrium?
By transferring heat from warmer to colder regions
What is one way in which cold ocean currents impact Earth's climate?
By cooling down temperate zones they flow through
