If an area is in the 50+ dBZ range, what atmospheric pressure conditions could the area be experiencing?
monitta

The atmospheric pressure conditions for a 50+ dBZ range differs from small to heavy hails.

Explanation:

dBZ refers to decibel relative to Z used in weather radar most of the times, in order to compare the reflection factor (Z) of a weather radar signal reflected off a remote object  to the return of a droplet of rain with a diameter of 1 mm.

dBZ is a logarithmic dimensionless technical unit, at 55 dBZ and above, most storms have hail which can throw off the rainfall rate because hail has a higher reflection.

Generally above 50 dBZ range the intensity varies accordingly for every 5 points. Such as small hail to moderate hail and from moderate to heavy hail.

Therefore the atmospheric pressure conditions differs from rains to hails.

The growth of a population of sparrows accelerates with each generation. the chances of dying are about the same for these sparr
Paladinen [302]

Answer:

Exponential growth and a type II survivorship curve

Explanation:

  • Firstly we need to understand what exponential growth is, it is the type of growth in which population of any specie increases at a tremendous rate, constantly. In this type of growth, the increase is an exponential function of time for example, 2 reproduce to form form, four to sixteen and so on.

Population survivorship curves are simply the graphs representing increase in population with respect to time. There are three types of population survivor ship curve, Type I, Type II and Type III.

  • <u>In Type II survivorship curve,</u><u> </u>there is a constant dying rate of individuals of population with respect to time.

Now lets come back towards question, where two characteristics of the population are mentioned,

  1. Exponential growth of a population of sparrows with each generation.
  2. Constant dying rate

<em>This clarifies that </em><u><em>Exponential growth and a type II survivorship curve</em></u><em> is the best option representing the said scenario.</em>
