The Moon's Impact on Earth: How the Moon Shapes Our Planet’s Systems

In The Moon's Impact on Earth: How the Moon Shapes Our Planet’s Systems, learn how the Moon plays a crucial role in Earth’s tides, climate, and seasons. Meet Jerry Wiant who uses a laser to measure the Moon’s distance from Earth at the McDonald Observatory in West Texas, revealing that the Moon is receding at a rate of 3.8 cm/year. This information helps us understand the Moon's influence on Earth and the long-term effects of its gradual movement away from the planet. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary that explores the fascinating geology on planet Earth.

Lesson Express

Q: What impact does the Moon have on Earth’s tides and climate?
A: The Moon causes tides and helps stabilize Earth’s climate. Without the Moon, Earth would experience extreme temperature swings, making it difficult for life to survive.

Q: Why is it important that the Moon is receding from Earth?
A: The Moon’s gradual movement away from Earth provides insight into the Earth-Moon system and helps scientists understand the long-term effects on the planet’s stability and climate.

Q: How is the Moon’s distance from Earth measured?
A: The Moon’s distance is measured by firing a laser through a telescope at a reflector on the Moon and calculating the time it takes for the light to return.

The Moon and Lunacy: Myths vs. Science

In The Moon and Lunacy: Myths vs. Science, host Harith Iskander debunks myths that connect the Moon's phases to human behavior, particularly the idea of "lunacy" or madness. The Moon's gravitational pull does influence tides, but it does not have an effect on the water in our bodies, despite common myths. Learn about the Moon’s gravitational force and its real effects on Earth, as well as the science that dispels these longstanding myths. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
