On 21st June, northern hemisphere appears :
ans: Inclined towards the sun
Fill in the blanks :
1. Seasons are caused due to the revolution of the Earth.
2. The circle that divides the day and night on the globe is called the Circle of illumination
3. The period of rotation is known as EQUINOX
4. The longest day and shortest night in the northern hemisphere occurs on 21 june
5. The Earth travels around the sun in a fixed elliptical orbit.
True / False :
1. Norway is called the land of the midnight sun.
Ans: true
2. Rotation is the annual movement of the Earth.
Ans: False
3. Revolution causes day and night.
Ans: False
4. 23rd September is equinox.
Ans: False
5. The early period between darkness and sunrise is called dawn.
Distinguish between the following:
K Dawn and Twilight
Ans: Dawn occurs before sunrise, before the top of the Sun reaches the horizon. ... Twilight is the name given to the period between dawn and sunrise, or between sunset and dusk
Equinox and Solstice
Ans: The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator
Rotation and Revolution of the Earth
Ans: Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
Sunrise and Sunset
Ans: "Sunrise" occurs the moment the disc of the sun peeks above the eastern horizon due to the Earth's rotation. "Sunset" is the opposite. It occurs the moment the disc of sun completely disappears below the western horizon.
21st March and 23rd September
Ans: On 21st March and September 23rd, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun; so, the whole earth experiences equal days and equal nights. This is called an equinox.
