World & Physical Geography MCQs

Notes:
The solstice refers to the events when the Sun’s apparent position in sky reaches its northernmost or southernmost extremes. Solstice happens twice a year, and twice a year happen the equinoxes. Altogether, the four are considered to start 4 seasons.

• At the time of northern solstice, sun is perceived to be directly overhead the 23.44° north known as Tropic of Cancer.
• Likewise, at the southern solstice the same thing happens for latitude 23.44° south, known as the Tropic of Capricorn.

Notes:
The congo river crosses equator twice. It is the second longest river in Africa after Nile.

Notes:
The Acasta Gneiss is located in the Northwest Territories of Canada. The rock is exposed on an island about 300 kilometers north of Yellowknife. The Acasta Gneiss is one of the oldest known intact crustal fragments on Earth. The rock was metamorphosed between 3.58 and 4.031 billion years ago.  The Acasta Gneiss was first described in 1989. It was discovered during fieldwork in 1983 by Geological Survey of Canada geologist Janet King.  Gneiss is a type of rock that has been metamorphosed by intense heat and pressure at depth in Earth’s crust. The original, unmetamorphosed rock was a granite, an intrusive igneous rock.

Notes:
Equinox occurs when center of Sun and Earth’s equator are in same plane.

Notes:
Baobab is also known as the ‘Tree of Life’. Baobab is capable of providing shelter, clothing, food, and water for human inhabitants and animals of the African Savannah regions.

Notes:

Notes:
Indus is a constellation in the southern sky. The name of the constellation means the “Indian” and it is illustrated as a man holding arrows without a bow.

Notes:
Spectroscope is used to measure the chemical composition of the stars. It is also used to measure the temperature and direction of the star moving in relation to the Earth.

Notes:
The color of the star determines its temperature. Red stars are the coolest stars ( approx 3000 degree celsius). The blue stars are the hottest stars .i.e. more than 15000 degree celcius. Our sun is a yellow star with temperature ranging from 5500 – 6000 degree celsius.
