Green house effect is the trapping of heat by some gases ! mainly in our earth this is increasing due to CO2 !
Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.
Answer:
Zagros Mountains
Explanation:
The Zagros Mountains are one of the most dominant geographic features in the Middle East. This mountain range has length of roughly 1,600 km. There are three countries through which the Zagros Mountains are stretching, those being Turkey, Iraq, and Iran. The majority of the Mountain range runs through Iran, making up big portion of the border with Iraq, as well as being a natural barrier at the southern coast of the country.
These mountains have elevation of over 4,400 meters above see level. They are responsible for the dry climate in Iran, as they are a big natural barrier for the air masses, so they create a rain shadow, making the interior of Iran very dry.
