Seasons on Earth: Seasons Earth Moon And Sun Gizmo Answer Key Pdf
Earth’s seasons are caused by the tilt of its axis of rotation. As the Earth orbits the Sun, different parts of the planet are tilted towards or away from the Sun, resulting in variations in the amount of sunlight received and the length of day and night.
During the summer solstice, the North Pole is tilted towards the Sun, resulting in longer days and shorter nights in the Northern Hemisphere. The opposite occurs during the winter solstice, when the North Pole is tilted away from the Sun, resulting in shorter days and longer nights in the Northern Hemisphere.
The Earth’s Position Relative to the Sun During Each Season, Seasons earth moon and sun gizmo answer key pdf
- Spring:The Earth’s axis is tilted neither towards nor away from the Sun, resulting in equal day and night lengths at all latitudes.
- Summer:The North Pole is tilted towards the Sun, resulting in longer days and shorter nights in the Northern Hemisphere.
- Autumn:The Earth’s axis is tilted neither towards nor away from the Sun, resulting in equal day and night lengths at all latitudes.
- Winter:The North Pole is tilted away from the Sun, resulting in shorter days and longer nights in the Northern Hemisphere.
Seasonal Changes in Day Length and Temperature
- Day length:During the summer, days are longer in the Northern Hemisphere and shorter in the Southern Hemisphere. The opposite occurs during the winter.
- Temperature:During the summer, temperatures are generally warmer in the Northern Hemisphere and cooler in the Southern Hemisphere. The opposite occurs during the winter.
The Moon’s Orbit
The Moon orbits the Earth in an elliptical path, taking approximately 27.3 days to complete one orbit. The Moon’s orbit is not perfectly circular, so its distance from the Earth varies throughout its orbit.
The Different Phases of the Moon
The Moon’s phases are caused by the changing positions of the Moon, Earth, and Sun. As the Moon orbits the Earth, different parts of the Moon are illuminated by the Sun, resulting in the different phases of the Moon.
- New Moon:The Moon is between the Earth and the Sun, and the side of the Moon facing the Earth is not illuminated.
- Waxing Crescent:The Moon is moving away from the Sun, and a small sliver of the Moon facing the Earth is illuminated.
- First Quarter:The Moon is at a right angle to the Sun, and half of the Moon facing the Earth is illuminated.
- Waxing Gibbous:The Moon is moving closer to the Sun, and more than half of the Moon facing the Earth is illuminated.
- Full Moon:The Moon is opposite the Sun, and the entire side of the Moon facing the Earth is illuminated.
- Waning Gibbous:The Moon is moving away from the Sun, and more than half of the Moon facing the Earth is illuminated.
- Third Quarter:The Moon is at a right angle to the Sun, and half of the Moon facing the Earth is illuminated.
- Waning Crescent:The Moon is moving closer to the Sun, and a small sliver of the Moon facing the Earth is illuminated.
The Moon’s Effect on Tides
The Moon’s gravity exerts a pull on the Earth’s oceans, causing tides. The Moon’s gravity is strongest on the side of the Earth facing the Moon, and weakest on the side of the Earth facing away from the Moon.
This difference in gravitational pull causes the oceans to bulge out on the side of the Earth facing the Moon and on the opposite side of the Earth. These bulges in the oceans are called high tides.
The Sun’s Energy
The Sun’s energy is produced by nuclear fusion reactions in its core. In these reactions, hydrogen atoms are combined to form helium atoms, releasing a tremendous amount of energy.
The Different Types of Electromagnetic Radiation Emitted by the Sun
The Sun emits a wide range of electromagnetic radiation, including visible light, ultraviolet radiation, and X-rays.
- Visible light:This is the light that we can see with our eyes. It makes up about 40% of the Sun’s total energy output.
- Ultraviolet radiation:This radiation has a shorter wavelength than visible light and can be harmful to living organisms. It makes up about 10% of the Sun’s total energy output.
- X-rays:This radiation has the shortest wavelength of all the electromagnetic radiation emitted by the Sun. It makes up about 1% of the Sun’s total energy output.
The Sun’s Importance to Life on Earth
The Sun is the primary source of energy for life on Earth. The Sun’s light provides the energy that plants need to photosynthesize, and the Sun’s heat warms the Earth’s atmosphere and oceans.
