Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Global warming is a gradual increase in the earth's temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
With proportional representation? Simple. A multiparty system.
<u>Answer:</u>
<em>The movement of tectonic plates forms the different landforms in the planet. </em>
<u>Explanation:</u>
<em>The main cause for the volcanic activity is also the movement of plates under the earth’s surface. </em>
When the tectonic plates collides and are separated apart then the gap formed in the earth’s crust give the pathway for the magma to spill out, this causes the volcano to erupt and changes the landform of that place.
<em>The folding of the plates causes the rise in the land form which is called as the mountains.</em>
