The Sun is the primary source of radiant energy that emits electromagnetic radiation toward Earth's surface, including visible light, infrared radiation, and ultraviolet radiation. This energy is essential for sustaining life on Earth through processes like photosynthesis and heating the planet.
When a wave is coming toward a surface, it is called an incident wave.
Gravity pulls the earth and anything on its surface together, toward each others' centers.This is important to understand:-- There is a pair of gravitational forces between you and the Earth.-- One force pulls you toward the center of the Earth.The other one pulls the Earth toward the center of you.-- The forces are equal.Your weight on Earth is the same as the Earth's weight on you.
The magnitude of the incident angle with the normal of the reflection surface and reflection angle with the normal of the surface are the same. The direction of the reflection is away form the surface and the incident is toward the surface.
Wind pushes against the surface of the water, creating friction and transferring its energy to the water. This energy causes the water molecules to move and transmit the motion to neighboring molecules, generating a ripple effect known as surface waves. These surface waves then travel toward the shore, carrying the energy of the wind with them.
As the penny falls toward the ground, potential energy is converted to kinetic energy. Potential energy is stored energy based on an object's position or shape, while kinetic energy is the energy of motion.
Yes.
Infrared (or radiant heat).

Heat from the Earth rises to the surface because heat rises. Heat rises because it is energy and the atoms are looking for more space to move freely in.
The dense air sinking towards the Earth's surface is called subsidence. Subsidence can lead to high pressure systems and stable weather conditions.
The buoyant force pushes you toward the surface.

The wavelength of radiant energy emitted by a source is inversely related to its temperature, described by Wien's displacement law; as the temperature increases, the peak wavelength of the emitted radiation decreases. This means hotter objects emit shorter wavelengths, moving from infrared toward visible light. In terms of solar-terrestrial radiation, the Sun, with a surface temperature of about 5,500°C, emits primarily in the visible spectrum, while the Earth, with a much lower temperature, emits infrared radiation. This difference is crucial for understanding how solar energy is absorbed and re-radiated by the Earth, influencing climate and energy balance.

Heat
The moon's gravitational pull creates tides on Earth's surface water. As the moon orbits, its gravitational force causes water to bulge out toward the moon, creating high tides. This effect is more noticeable in areas closer to the moon.
Only one hemisphere has summer at a time, either the Northern or the Southern, while the other has winter. This is determined by which hemisphere is tilted toward the Sun: except for two days each year (the equinoxes), the Earth's tilt means that one pole or the other is angled more toward the Sun. The tilt results in a combination of longer days than nights (more sunshine) and a lesser angle to the Sun's rays (closer to perpendicular to the surface). Less sunlight is refracted or scattered, and more energy reaches the surface than when the angle is greater.
