Answer:
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
Explanation:
1. Tectonic
2. Subtropical
3. Aborigine
4. Desalination
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>
The length is 88 cm, multiply the width by two and subtract it from the whole perimeter. Then divide the whole perimeter again by two to find the length of one side.
