1.
The vehicle exhausts contain large portion of
this colorless, odorless, and tasteless gas that is slightly less dense than
air. Although it is produced in normal animal metabolism in low quantities,
when encountered in concentrations above about 35 ppm it can be toxic to
humans. When inhaled it is absorbed by blood in the lungs and forms a stable
compound upon combining with the haemoglobin in the blood, resulting in reduced
ability of blood to transport oxygen to different parts of the body. Name this
gas.
a.
Carbon Dioxide
b.
Ozone
c.
Carbon Monoxide
d.
Nitrogen
2.
Greenhouse effect occurs when the atmosphere of
a planet or satellite allows sunlight to pass through but traps the infrared
portion of the sunlight, resulting in net increase in the planet or satellite’s
surface temperature. However, on Titan (the satellite of Jupiter) the opposite
of greenhouse effect occurs, i.e., the atmosphere does not allow sunlight to
pass through and allows the infrared portion of the sunlight to escape,
resulting in net decrease in the planet or satellite’s surface temperature.
What is this phenomenon called?
a.
Whitehouse effect
b.
Anti-greenhouse effect
c.
Reverse-greenhouse effect
d.
Open-house effect

On 28-Jun-2007, this site in Oman became
historic as the first ever to be delisted and removed from the World Heritage
Site register. The reasons cited by UNESCO for delisting this site were: (i)
Oman's decision to reduce the site by 90%, and (ii) the decline of the
population of a threatened animal (Hint: the national animal of Oman), found in
the site, from 450 in 1996 to 65 as a result of poaching and loss of habitat.

A sinkhole, also known as a sink, shakehole,
swallet, swallow hole, or doline, is a depression or hole in the ground caused
by some form of collapse of the surface layer. Sinkholes are common where the
rock below the land surface is limestone or other carbonate rock, salt beds, or
gypsum that can be dissolved naturally by circulating ground water. As the rock dissolves, spaces and caverns
develop underground. These sinkholes can be dramatic, because the surface land
usually stays intact until there is not enough support. Then, a sudden collapse
of the land surface can occur. In Oman a popular sinkhole is the Bimmah
Sinkhole that lies on the Muscat-Sur road. Name the lesser known sinkhole
located in Dhofar region, which is one of the largest sinkholes of the world.

Tayq Sinkhole
