Economic geography is the study of the location, distribution and spatial organization of economic activities across the world. It represents a traditional subfield of the discipline of geography. However, many economists have also approached the field in ways more typical of the discipline of economics

Answer:
1.0236 billion metric tons
Explanation:
Given Parameters
Number of cars = 300000000
Average gas mileage per car = 25 MPG
Average distance covered by a car in one year = 10000 miles
CO2 Emission = 8.53 kg/gallon
Derivations from the given parameters,
If the average gas mileage per car is 25 MPG, then the volume of fuel consumed by a car in a year is:
<em>10000 miles ÷ 25 MPG = 400 gallons
</em>
The CO2 emission for one car in a year is:
<em>400 gallons × 8.53 kg/gallon = 3412 kg or 3.412 metric tons (note: 1000 kg = 1 metric ton)
</em>
The CO2 emission for 300000000 cars in year is:
<em>3.412 metric tons × 300000000 = 1023600000 kg = 1.0236 billion metric tons
</em>

A. True, is the answer, hope this helps :,)
Answer:
Factors includes :
Climate changes
Dissolved Oxygen
Explanation:
Climate change is one factor that causes migration of marine life from tropic water to colder water due to global warming in search of warms around them. This animals are moving towards the poles to escape the heat.
Climates changes is also a factor that affect ecosystem of marine animals along the ocean/continent margin. As global temperature increases, sea level rises and currents will be affected pushing nutrient to the shores of oceans.
Dissolved oxygen , As temperature increases the solubility of oxygen decreases. Therefore, dissolve oxygen is more present in colder water than warm water. The abundant availability of dissolved oxygen thereby drives marine animal to colder water.
