The magnetized needle of a compass usually does not point towards the geographical North Pole, or true north. Rather, it aligns itself with the direction of the Earth's magnetic field, showing magnetic north. In most locations on Earth, magnetic north differs from true north, so magnetic declination has to be taken into account.
Magnetic declination is expressed in degrees east or west. A western declination is usually stated as a negative value while an eastern declination is represented by a positive value. For example, in Florida, magnetic north currently lies around 6 degrees west of true north, so the Sunshine State has a magnetic declination of -6°.
That bug was types of new. but according to scientific research that bug called Fisomynon) it has VENUS poison if this bug bite us. by the way FISOMYNON) or known as a Tillas cocroach.
About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on
The sun rays reach the earth's surface at an angle of 90 degrees at the equator which is direct and is short as compared to the poles it's long and about 66.5 degrees to the south and north. In the tropics its falls as 23.5 degrees in the northern and southern hemisphere.
The sun rays that form a tangent to the northern hemisphere are at 0, 23.5, 66.5 degrees i.e tropics, temperate and poles. And same is for the southern hemisphere.
On June 21 the southern hemisphere has winter seasons as the amount of insolation that reaches the southern side is less due to the tilt of the sun.
