Scheme implemented under the Ganga Action Plan is ________________.
-
Waste water treatment
-
Electric crematorium
-
River front development
-
All of these
The Ganga action plan was, launched by Shri Rajeev Gandhi, the Prime Minister on 14 Jan. 1986 with the main objective of pollution abatement, to improve the water quality by interception, diversion and treatment of domestic sewage and present toxic and industrial chemical wastes from identified grossly polluting units entering into the river.
The term "Bore" signifies _____________.
-
To drill a well
-
a wave caused by tides
-
a wave cause by air
-
To extract water from earth
A tidal bore, often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay against the direction of the river or bay's current.

-
$180^o$
-
$90^o$
-
$45^o$
-
$33^o$
The spring tide occurs when the moon, the sun and the earth make in angle of $180^0$.
Neap tides are produced in the first and third quarters of the moon. Then _______.
-
Moon and the Sun are in conjunction with the other planets
-
Moon and the Sun are in opposition with each other
-
The attractions of the Sun and the Moon are at right angles to each other
-

Neap tides are produced in the first and third quarters of the moon. Then the attractions of the Sun and the Moon are at right angles to each other.
The difference between high tide and low tide is __________.
-
Tidal range
-
Tidal width
-
Tidal height
-
None of these
- Tides are the rise and fall of
sea level caused by the combined effects of gravitational forces exerted by sun, moon and earth.
- Tidal range is the vertical difference
between high tide and its succeeding low tide.
The average time interval between successive high tide and low tide is _____.
-
12 hours and 26 minutes
-
6 hours and 12 minutes
-
24 hours and 52 minutes

50 minutes
Which waves caused by the earthquakes cause maximum damage and destruction on earth's surface?
-
P waves
-
S waves
-
Distortional waves
-
Surface waves
During an earthquake, surface waves cause the most damage. Unlike other seismic waves that move deep inside the Earth, surface waves move along just under the surface of the Earth like waves in water. Surface waves are the slowest seismic waves and are the final waves to hit an area after an earthquake.
First, P-waves move through compression through the deep layers of the Earth. P-waves are also carried by air and water, causing them to make a sound when they hit the Earth's surface. They result in minimal damage. The second group of waves is S-waves. They move up and down starting deeper in the Earth, and they cannot travel through air or water. Stronger S-waves do some damage when they reach the surface. Surface waves move in last. Their slow roll just under the surface provides the greatest risk for damage to man-made structures and changes to natural landforms.
Ocean waves are used for generating ______.
-
light
-
power
-
food
-
wind
During full moon _________ tides occur.
-
neap
-
spring
-
high
-
low
When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.
On new moon and full moon days _______ occurs.
-
neap tide
-
spring tide
-
high tide
-
low tide
