Test: General Physical Geography- 2 - Class 5 MCQ

Sudden fall in barometer reading indicate stormy weather. Storms are created when a center of low pressure develops with a system of high pressure surrounding it. It may be marked by significant disruptions to normal conditions such as strong wind, tornados, hail, thunder and lightning.

Anaimudi  is highest peak of Peninsular India.

Since mid-day sun is almost overhead through­out the year and there is little difference between the lengths of day and night during the year. The average temperatures vary during the year by 2.2 °C. The climate is warm and temperate with  significant rainfall throughout the year.

Magnetic meridian is a continuous imaginary line around the surface of the earth passing through both magnetic poles. It can be taken as the horizontal component of magnetic force lines along the surface of the earth. A compass needle without deviation lies in the magnetic meridian.

Metamorphism is a process in which the original rock when subjected to heat and pressure changes its form. Some of the examples of this transformation are: gneiss is formed from granite, slate from shale, marble from limestone, quartzite from sandstone, etc.

Albedo is a measure of reflection of solar radiation out of the total solar radiation incident on a body. It is measured on a scale of 0 to 1. Earth's albedo is about 0.30, which means it reflects almost 30% of the solar radiation incident on it. 

It takes approximately 27 days for the moon to complete 1 revolution around the earth and it takes the same amount of time for it to complete 1 rotation on its own axis. As a result of this, we always see the same face of the moon.

Stalactites and stalagmites are both rock formations which may be composed of minerals, lava, pitch, sand etc. Stalactites hang as icicles from the ceilings of the caves and may be of different diameters. Stalagmites rise from the floor of the caves and are formed due to accumulation of material dropped from the stalactites.

Chilika lake is brackish water lagoon , spread over the Puri , Khurda and Ganjam districts of Odisha state on the wast coast of India , at the mouth of the Daya River , flowing into the Bay of Bengal , covering an area of over 1,100Km²

Stars are like giant nuclear reactors in which fusion processes lead to release of a lot of energy which is responsible for the hotness and brightness of the stars. During fusion, smaller hydrogen nuclei combine to form bigger helium nuclei. 

A solar flare is sudden, rapid and intense variation in Sun's brightness and is caused due to the sudden release of magnetic energy. The flare ejects cloud of ions, electrons, atoms along with the electromagnetic waves through the Sun's corona into the outer space.

White dwarfs are very small in size, comparable to that of earth, but they are quite dense and their mass is quite large, comparable to that of Sun. Their luminosity comes from the stored thermal energy. The nearest known white dwarf is Sirius B, about 8.6 light years away from earth.

Black hole is a place in space in which matter has been squeezed in a tiny place and gravitational pull is thus so high that even light cannot escape the black hole. Because no light can escape black holes, they are invisible. Black holes are generally formed towards the end of a star's life.

The concept of a leap year is basically a corrective measure as the length of a year is not 365 days, but about 365.25 days. This is adjusted in our length of a year every 4 years when 1 more day is added to the month of February.

The latitude denotes a geographical coordinate of a place located on the surface of the earth and is the angular distance of that point (north or south of the equator) measured with respect to the Centre of the Earth. Its value is zero at equator and 90 degrees at poles.
