The answer is D. 1.3 billion
Answer:
b. wind waves, seiches, tsunami, tides.
Explanation:
The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave. Usually, the bigger the wave, the greater the wavelength.
wind waves: small waves caused by the wind. These waves tend to be small and with a short wavelength.
seiches: are usually waves on a lake or other closed water bassin. They can be pretty high from a human perspective, so they are definitely bigger than wind waves.
tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.
tides: yes, a tide can be considered as a huge wave... that's running throughout the planet. We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.
Answer:
Explanation:
Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate.
Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees.
