__________is not associated with climate change.

What can be done to prevent climate change?

__________ is a greenhouse gas.

• They are referred to as greenhouse gases because, like the glass of a greenhouse, they let visible light from the Sun pass through the atmosphere and they absorb long-wavelength infrared energy from the Earth and keep the atmosphere warm.
• Greenhouse gases include carbon dioxide, methane, nitrous oxide and other gases that accumulate in the atmosphere and create the heat-reflective layer.

Which of the following is explained by theory of plate tectonics?

• Big Bang theory explains how the universe began.
• Gravity is not same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense and also due to it's rotation.
• Since the forces that generate our magnetic field are constantly changing, the field itself is also in continual flux, its strength waxing and waning over time.

Due to the divergence of plates, magma from the mantle to reach the surface of the Earth as____.

The main causes of sea level rise is ___________.

Identify the plate boundary.

• This motion does not create or destroy crust and will cause earthquakes, but no volcanoes.

In some volcanic eruptions, mudflows are forced over the__________.

• Volcanic mudflows, are hot or cold mixtures of water, rock, sand, and mud moving down the flanks of a volcano and running away from it. 

Large pieces of outer crust that float on the upper mantle is__________.

• Tectonic plates float on the asthenosphere, which is the uppermost layer of the mantle. 

Cool magma _________whereas hot magma_________.

________is the strongest evidence for climate change.

At a transform boundary_________.

The movement of Magma due to the convection current results in the movement of the __________.

At the _____________________, earthquakes and volcanic eruptions mainly take place.

• Tectonic activity such as earthquakes, volcanic eruptions and the formation of mountain ranges commonly occurs along the boundaries of the moving plate.

The following image shows____________.

In which of the following movement, plates move towards each other, and they collide?
