Some observable phenomena and patterns on Earth caused by the movements of the Sun, the Earth, and the Moon.：練習問題

During the day, the Sun appears to move across the sky from one side to the other. What direction does the Sun appear to rise from each morning?

Earth's axis is not perfectly straight up and down relative to its orbit. As shown in the diagram, Earth is tilted at an approximate angle of ________.

Which alignment of celestial bodies is responsible for a solar eclipse?

The Moon does not produce its own light like a lamp. Why does it glow in the night sky?

It takes approximately \( 365.25 \) days for Earth to complete one full revolution around the Sun. How does our calendar system account for the extra \( 0.25 \) day each year?

The Earth is tilted on its axis as it revolves around the Sun. What repeating yearly pattern of weather and temperature changes does this tilt cause on Earth?

Explain how the Earth's orbit around the Sun leads to the observation that the Sun's highest point in the sky (at noon) changes throughout the year, affecting how direct sunlight is received.

Explain why coastal areas typically experience two high tides and two low tides each day, relating this pattern to the gravitational pull of a celestial body.

The Moon's appearance changes in a predictable monthly pattern known as lunar phases.
a) What is the name of the phase when the side of the Moon facing Earth is completely illuminated by the Sun?
b) What is the name of the phase when the Moon is located between the Earth and the Sun, making it invisible to observers on Earth?
c) Briefly explain why we always see the same side of the Moon from Earth, even as it orbits our planet.

Earth's journey around the Sun is combined with a specific tilt of its axis, which leads to various patterns.
a) How long does it take for Earth to complete one full revolution around the Sun?
b) Imagine Earth's axis was not tilted at all (standing perfectly straight). Explain why we would no longer experience a change in seasons throughout the year.
c) Describe how the intensity of sunlight reaching a specific hemisphere changes when it is tilted toward the Sun compared to when it is tilted away.
