How do human activities impact Earth's wobble?
Press to flip
Activities such as water use and ice melting can influence Earth's axis wobble.
What event marks the beginning of the Solar System's formation?
The collapse of the solar nebula, a cloud of gas and dust.
What is the significance of the Earth's 365.25-day orbit around the Sun?
This duration defines a year and is why we add a leap day every four years.
Explain the concept of Earth's precession.
Precession is the wobbling of Earth's axis, occurring in a 26,000-year cycle.
What inspired Alizé Carrère to develop an understanding of Earth's dynamics?
Growing up in a house built around a 300-year-old oak tree and living in harmony with nature.
How do Earth's movements influence human lifestyles and survival strategies?
The dynamics of Earth's movements affect climate and geography, leading humans to adapt in terms of agriculture, architecture, and resource management.
What is the approximate speed of Earth's rotation at the equator?
~1600 km/hr.
Describe the Sun’s apparent movement in the sky.
The Sun's apparent movement is due to Earth's rotation on its axis.
Explain why the length of day and night are equal during equinoxes.
During equinoxes, Earth's tilt is such that the Sun is directly above the equator, resulting in equal day and night lengths.
How does Earth's elliptical orbit affect its distance from the Sun?
The elliptical shape causes the distance from the Sun to vary during Earth's orbit.
What role does Earth's axial tilt play in climate and weather patterns?
The 23.5-degree axial tilt determines sunlight distribution, influencing seasons and climate patterns.
What are the Milankovich Cycles and their significance?
They are cycles that affect Earth's climate through variations in solar energy received, influenced by Earth's movements.
How long ago did the universe begin according to the notes?
13.7 billion years ago.
What happens during the December solstice?
The Southern Hemisphere experiences summer, while the Northern Hemisphere experiences winter.
Why do we experience different seasons on Earth?
Seasons are caused by Earth's axial tilt and its elliptical orbit around the Sun, not the distance from the Sun.
