The answer is
Longitudinal waves.
The particle displacement in a longitudinal wave is
parallel to the direction of wave propagation. The ground particles simply oscillate
back and forth their equilibrium positions unlike transverse waves that do not
move along with the waves but rather oscillate up and down their individual
equilibrium positions.
Answer:
Definition: declination is the angular distance of a point north or south of the celestial equator.
The declination angle, denoted by δ, varies seasonally due to the tilt of the Earth on its axis of rotation and the rotation of the Earth around the sun. If the Earth were not tilted on its axis of rotation, the declination would always be 0°. However, the Earth is tilted by 23.45° and the declination angle varies plus or minus this amount. Only at the spring and fall equinoxes is the declination angle equal to 0°. The rotation of the Earth around the sun and the change in the declination angle is shown in the animation below. It more or less affects the actual time of sun rise/set, but not the length of day
Answer:
With the spread of smallpox, the Native American population declined causing overall levels of population in North America and South America to decrease.
It's the best explanation on there.
Answer:
Bright parts of Earth like snow, ice, and clouds, reflect the most light; dark surfaces, like the oceans, reflect less light.
Explanation:
- Shortwave radiation is not absorbed in the ocean’s surface skin layer, but instead penetrates to 1–100 m. The absorption decreases exponentially with depth.
-
Shortwave radiation originates mainly as light from the sun. The light that makes it through the atmosphere to the land surface is mostly absorbed, but some is reflected. Open water absorbs nearly all the sunlight falling upon it.
- Fresh snow is the most highly reflective natural substance on the land surface, reflecting over 80% of solar radiation, but snow progressively absorbs more radiation as it ages and compacts. These spatial and temporal variations in land-surface reflectivity have huge consequences for the surface energy balance and the distribution of surface heating.
