Our Changing Earth Test - 2

The steep rocky coast rising most vertically above the sea water is called sea cliff. The sea waves deposit sediments along the shores forming beaches.

Volcano is caused by the sudden movements of the earth. A volcano is a vent opening in the earth’s crust through that molten material erupts suddenly.

Sand dunes are low hill-like structures formed by the deposition of sand in the deserts.

These plates move around very slowly – just a few millimetres each year. This is because of the movement of the molten magma inside the earth. The molten magma inside the earth moves in a circular manner.

An active agent of erosion and deposition in the deserts is wind. In deserts rocks are in the shape of a mushroom, commonly called mushroom rocks.

When the meander loop is cut off from the main river it forms a cut-off lake. As its shape is like an ox-bow, it is also known as ox-bow Lake.

The 2001 Gujarat earthquake, also known as the Bhuj earthquake, occurred on 26 January, India's 51st Republic Day, at 08:46 AM IST and lasted for over 2 minutes

Victoria Falls is in Africa. It is on the borders of Zambia and Zimbabwe in Africa.

The earth movements are divided on the basis of the forces which cause them. The forces which act in the interior of the earth are called as Endogenic forces and the forces that work on the surface of the earth are called as Exogenic forces

Lithospheric plates are regions of Earth's crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle. Earth's crust is fractured into 13 major and approximately 20 total lithospheric plates.These plates move around very slowly – just a few millimetres each year. This is because of the movement of the molten magma inside the earth. The molten magma inside the earth moves in a circular manner.

The material carried by the glacier such as rocks big and small, sand and silt gets deposited. These deposits form glacial moraines.

An earthquake is measured with a machine called a seismograph. The magnitude of the earthquake is measured on the Richter scale

Endogenic forces sometimes produce sudden movements and at the other times produce slow movements. Sudden movements like earthquakes and volcanoes cause mass destruction over the surface of the earth.

The epicenter is the point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.

An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves.When the Lithospheric plates move, the surface of the earth vibrates. The vibrations can travel all round the earth. These vibrations are called earthqauake.

The 2001 Gujarat earthquake, also known as theBhuj earthquake, occurred on 26 January, India's 51st Republic Day, at 08:46 AM IST and lasted for over 2 minutes.. The intraplate earthquake reached 6.9 on the Richter scale.
Thus, Bhuj is in Gujarat

EARTHQUAKE PREPAREDNESS
Where to take shelter during an earthquake — Safe Spot – Under a kitchen counter, table or desk, against an inside corner or wall.
Stay Away from – Fire places, areas around chimneys, windows that shatter including mirrors and picture frames.
Be Prepared – Spread awareness amongst your friends and family members and face any disaster confidently.

So, all other statements are true except this statement.

In due course of time the meander loop cuts off from the river and forms a cut-off lake, also called an ox-bow lake.

The sea waves deposit sediments along the shores forming beaches. The erosional features of sea waves are a cliff, sea cave and stacks.

During floods, layers of fine soil and other material called sediments are deposited on the river banks. This leads to the formation of a flat fertile flood plain.

The earth movements are divided on the basis of the forces which cause them. The forces which act in the interior of the earth are called as Endogenic forces and the forces that work on the surface of the earth are called as Exogenic forces

The plates move because the movement of magma inside the earth.

A volcano is a vent (opening) in the earth’s crust through which molten material erupts suddenly

The point on the Earth's surface located directly above the focus of an earthquake. Focus-The location where the earthquake begins.Thus,the place in the crust where the movement starts at the time of earthquake is called the focus.

Erosion is the wearing away of the landscape by different agents like water, wind and ice.

the forces that work on the surface of the earth are called as Exogenic forces
Following are external forces
1.River
2.Wind
3.Sea-waves
4.Glacier
5.Erosional and Depositional
Thus, volcano is not external or exogenic force.

There are thousands of small waterfalls in the world. The highest waterfall is Angel Falls of Venezuela in South America.

Beaches are formed when the sea waves deposit sediments along the shores of the sea.
