The equator lies in between these two tropics. .And more importantly ,earth being a spherical ball, the equatorial area protude outside in comparison to the tropics.
It's estimated that the radius of Earth’s equatorial circle, is 6378 km and that of tropical circles are 5,852 km. Thats a good 526 kilometres difference. It means the equator is 526 kilometres nearer to the Sun than the Tropics.This also results in hotter equatorial region.
2. place on Earth where you can go back in time? Okay, not really go back in time, but it's almost the same thing. When you cross the International Date Line, the date changes. What's happening here? You've probably noticed that different places on Earth have different times. If one person in New York and another in California are talking on the phone, the time for each is different. Three hours different, to be exact. This is because New York and California are in different time zones.
At any given time, the sun is shining on some part of the earth. In fact, if you left your home at noon and ran westward at over 1000mph, you would outrun the sun and it would seemingly never set. Time zones are a way to make everyone's daylight hours roughly the same, so the sun rises in the morning and sets in the evening no matter where you live (with a few exceptions, but we won't worry about those right now).
The earth is divided into slices that run from pole to pole, kind of like an orange. The imaginary lines that divide these slices are called lines of longitude. Anything circular, like a sphere, can be divided into 360 degrees. The earth is roughly a sphere, and therefore can be divided into 360 equal slices. We give time zones their own sections 15 degrees wide.
If you do the math, 360 divided by 15 is 24, so there are a total of 24 different time zones. Each one increases by one hour if you go east or decreases by one hour if you go west. 24 hours in a day, 24 time zones. Easy, right? Well, eventually you will have to start over, and this is where it gets a bit weird. If you travel all the way around the world, you will eventually reach a line where you leap backward or forward a day.

The time in India has been UTC+5:30 (GMT+5:30) since 1945. Since India was still a British colony back then, that choice of time zone was probably made by the British government, and since independence, no Indian government has chosen to change it.
All land on Earth is currently divided into standard time zones, and every national government chooses the time zone(s) of the lands under its jurisdiction. The time zone chosen for an area loosely corresponds to a longitude through or near the area, with every 15° of longitude from the Prime Meridian corresponding to an hour of offset from Coordinated Universal Time (UTC).
4.1) The Frigid Zone :- It is divided into two sub-zones.
a) The North Frigid Zone :
It lies between the Arctic Circle 66.5 degrees North and the North Pole 90 degrees North. It covers 4.12 % of the Earth's surface.
b) The South Frigid Zone :
It lies between the Antarctic Circle 66.5 degrees South and the South Pole 90 degrees South. It covers 4.12 % of Earth's surface.
2) The Temperate Zone : It is also divided into two sub-zones.
a) The North Temperate Zone :
It lies between the Tropic of Cancer 23.5 degrees North and the Arctic Circle 66.5 degrees North. It covers 25.99 % of Earth's surface.
b) The South Temperate Zone :
It lies between the Tropic of Capricorn 23.5 degrees South and the Antarctic Circle 66.5 degrees South. It covers 25.99 % of Earth's surface.
3) The Torrid Zone :
It lies between the Tropic of Cancer 23.5 degrees North and the Tropic of Capricorn 23.5 degrees South. It covers 39.78 % of Earth's surface.
6.A time zone is a region of the globe that observes a uniform standard timefor legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the sametime.
5.Latitude is determined by the angle between apoint on the earth's surface and the equator. To calculate the angle, draw a line from the point to the center of the earth and a line from the equator to the center of the earth.
Answer:
1.The sun is exactly vertical on tropic of cancer only on summer solstice(from Northern hemisphere's perspective) i.e. 21st of June. Thereafter the incidence of vertical rays starts descending towards south till 21st of December. On that date it's winter solstice ,the sunrays are vertical on the tropic of Capricorn and the tropic of cancer experiences it's shortest day of the year. Thereafter , it starts climbing north till 21st of June and cycle continues.
