Explanation:
The following choices are provided;
- Earthquakes release phosphorus.
- Phosphorus is carried in the rain that was evaporated from lakes.
- Human use of fertilizers releases phosphorus into the groundwater.
- Phosphorus is transpired.
The answer is; Earthquakes release phosphorus
Phosphorus is usually made less available to plants and to the rest of the ecosystem through runoffs. The washed-off phosphorus is deposited at the oceans- and seabeds with sediments. This phosphorus is made available again due to tectonic plate movements. Tectonic movements may cause earthquakes that expose these sediments to the earth’s surface.This uncovers the sedimentary rocks to agents of weathering and hence the elements are more available to living organisms on the surface.
Answer:
A police car's radar gun emits microwaves with frequency f. 1. =36 GHz. The beam ... waves at f. 2 . • Which frequency is higher, f. 1 or f. 2 ? • Calculate the difference f. 2. – f. 1 . 2. Page 3 ... The Doppler effect for EM waves is derived in ... velocity between source and observer. 4 ... The reflected waves have this shifted.
