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

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?

What change can be seen in living things as climate change?

Which of the following statement is correct?

________is the process of collision of two plates with different densities.

________ contains highest mountains and deep oceans.

• Oceans and mountains are formed by tectonic activity in the lithosphere.

________ is a sudden shaking of the earth’s crust.

• A hurricane is a tropical storm.
• A tornado is a violently rotating column of air touching the ground, usually attached to the base of a thunderstorm.
• A storm is an acute disturbance of the atmosphere that is coupled with the mighty wind and usually by heavy or light rain, snow, hail, sleet, or thunder and accompanied by lightning.

The plates and the upper part of the mantle come together to form a layer is called__________.

• The troposphere is the first and lowest layer of the atmosphere of the Earth.
• The exosphere is the outermost layer of atmosphere. 

Which of the following is formed by Oceanic Plates?

• There are seven major plates-
• African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.

At the boundaries the magma reaches to the surfaces and formation of ridges take place on which area?

• Where plates converge, one plate may move under the other causing earthquakes, forming volcanoes, or creating deep ocean trenches.
• Where plates diverge from each other, molten magma flows upward between the plates, forming mid-ocean ridges, underwater volcanoes, hydrothermal vents, and new ocean floor crust.
