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.

The boundary where two tectonic plates come together is called___________.

• A divergent boundary occurs when two tectonic plates move away from each other.

When the heated Magma flow onto the surface of Earth all through the fracture, cracks, and volcanoes, it is called as___________.

• Lava is the hot molten magma that reaches the Earth's surface through cracks and crevices during a volcanic eruption.
• This cools down and solidifies below the Earth's surface or on it to form rocks.

The word 'Tectonics' comes from __________.

The ________________ flows along the East Coast of North America till it is bounced to the right by westerly winds.

• The Gulf Stream is a strong ocean current that brings warm water from the Gulf of Mexico into the Atlantic Ocean.

________is the strongest evidence for climate change.

Select the currents that flow from lower latitudes to higher latitudes.

Salinity in ocean water decrease when_____________.

• Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region.
• As we move toward the poles, the region of rain decreases and with less rain and more sunshine, evaporation increases.
