Population Pyramid Expansive - pyramid with a wide base (larger percentage of people in younger age groups, indicating high birth rates and high fertility rates) and narrow top (high death rate and lower life expectancies). It suggests a growing population.
<u>Answer:</u>
Same age stars is a mark of a galaxy formed by collapse.
<u>Explanation:
</u>
- Before a galaxy is formed, the building material of the galaxy in a protogalactic cloud that is rotating at a great speed rapidly accumulates and collapses in itself owing to its own gravitational pull.
- With this collapse, globular clusters are formed away from the nucleus of the galaxy.
- These clusters give birth to halo stars more or less at the same time. Thus, the stars that are formed of the same age.
- Sometimes, the reference of the age of the stars is taken to determine the age of the entire galaxy.
Answer:
transmissivity =0.0001458235 m² / year
Explanation:
given data
discharge = 6,000 acre - feet/year = 0.001775566 cubic miles
width of aquifer = 1.8 miles
Gradient = 0.95%
to find out
what would be the average transmissivity of the aquifer
solution
we know that transmissivity formula that is
transmissivity = 
here Q is discharge and W is width and i is gradient
so put here value
transmissivity = 
transmissivity = 
transmissivity =0.0010383427 mile² / year
and we know 1 miles² = 2589988.11 m²
so
transmissivity =0.0001458235 m² / year
