Answer:
B. where tectonic plates meet
Explanation:
Most volcanoes occur near tectonic plate boundaries. For example, a large amount are found on the Ring of Firez connecting several plates.
Answer:
6926.4J
Explanation:
Given parameters:
Mass of iron = 200g
Initial temperature = 100°C
Final temperature = 22°C
Unknown:
Amount of heat transferred to the water = ?
Solution:
The quantity of heat transferred to the water is a function of mass and temperature of the iron;
H = m c Ф
m is the mass of the iron
Ф is the change in temperature
C is the specific heat capacity of iron = 0.444 J/g°C
Now;
insert the parameters and solve;
H = 200 x 0.444 x (100-22)
H = 6926.4J
Momentum can be defined as a matter or mass in motion
Earth is surrounded by a blanket of air called the atmosphere.
All living organisms depend on this atmosphere to survive as the atmosphere provide the necessary air that we breath and also protects us from the harmful radiations of the sun.
The atmosphere is mainly composed of four layers which are:
1- Troposphere which has the air that we breath
2- Stratosphere which has the ozone layer
3- Mesosphere
4- Ionosphere
