Answer:
increases as you approach the poles
Answer:
An asteroid is in circular orbit around the Sun. Its distance from the Sun is 7.3 times the average distance of Earth from the Sun. The period of this asteroid is C : 20 Earth years .
Explanation:
Kepler's law
T² ∝ R³
T = orbital period of the planet
R = semi major axis of the orbit.
Now
( T₁ / T₂ )² = ( R₁ / R₂ )³
T₁ = Earth time period = 1 year
T₂ = Asteroid time period
R₁ = The distance between Earth and Sun
R₂ = The distance between Asteroid and Sun
From the question ,
R₂ = 7.3 R₁
applying on the above equation ,
( T₁ / T₂ )² = ( R₁ / R₂ )³
( 1 / T₂ )² = ( R₁ / 7.3 R₁ )³
( 1 / T₂ )² = ( 1 / 7.3 )³
T₂ = 19.7 year
Hence ,
approximately T₂ = 20 years.
The period of this asteroid is C : 20 Earth years .
Hello! It’s not January or June, because one Hemisphere will be hot, while another one will be cold. November could work, but then it would get colder and colder from there. It has to be March, because that’s where the spring equinox begins, where the days are balanced and the temperature start to become moderate. The answer is C: March.
ANSWER IS:
A. Artificial translocation of organisms
B. Physical removal of organisms
D. Habitation modification
EXPLANATION:
Natural distributions of biomes are often severely modified by human activities through physical removal, habitat modification and artificial translocation of organisms.
Humans can alter natural distribution patterns astonishingly quickly
Artificial translocation of organisms :
It leads to introduction of exotic species that have an effect on crops and pets
Physical removal of organisms :
Physically organisms are removed by modification of landscape for civilization. It effects overall distribution patterns.
Habitat modification :
Habitat is the natural environment where an organism lives. Human activities are responsible for the alterations in the habitat of many organisms that leads to their extinction.
For example, because of tropical rain forest removal it leads to loss of 27 million acres of rain forest per year.
Ecosystem can also effects from rain forest removal. Biodiversity lost through extinction.
