| Question | Answer |
|---|---|
| The Earth spins along an imaginary line called the …………… | axis |
| The spinning of the Earth on its axis is called …………… | rotation |
| The movement of the Earth around the Sun is called …………… | revolution |
| The Earth rotates from …………… to …………… | west,east |
| The rotation of the Earth causes …………… and …………… | day,night |
| The Earth and other planets move around the Sun in a fixed path called the …………… | orbit |
| It takes …………… hours for the Earth to complete one rotation | twenty-four |
| It takes …………… days and …………… hours for the Earth to complete one revolution around the Sun | 365,6 |
| The imaginary line running through the center of the Earth, dividing it into two equal halves, is called the …………… | equator |
| The top half of the Earth that lies between the equator and the North Pole is called the …………… …………… | northern hemisphere |
| The bottom half of the Earth that lies between the equator and the South Pole is called the …………… …………… | southern hemisphere |
| The North Pole is the …………… point of the Earth | northernmost |
| The South Pole is the …………… point of the Earth | southernmost |
| A year has …………… days | 365 |
| The imaginary line around which a spinning top or the Earth spins is called the …………… | axis |
| Earlier, people believed that the …………… was at the centre of the universe | Earth |
| Due to the Earth's rotation from west to east, places in the …………… get to see the Sun first | east |
| The axis of the Earth is …………… at an angle | tilted |
| Both …………… and …………… of the Earth happen at the same time | rotation |
| The revolution of the Earth around the Sun and the …………… …………… of the Earth cause the change in seasons | tilted axis |
| The extra 6 hours, per year, are added every four years to form an extra day in ……………, which makes a …………… year | February leap |
| When the northern hemisphere tilts towards the Sun, it receives …………… rays from the Sun and has longer hours of …………… | direct sunlight |
| When the southern hemisphere is tilted away from the Sun, it receives …………… rays of the Sun and hence, less hours of …………… | slanted sunlight |
| From April to June, the …………… hemisphere of the Earth tilts towards the Sun | northern |
| From November to January, the …………… hemisphere is tilted away from the Sun | northern |
| When it is summer in the northern hemisphere, it is …………… in the southern hemisphere | winter |
| When India has summer, Australia has …………… | winter |
| The imaginary line at the centre along which a spinning top spins …………… actually exist | does not |
| The Earth spins on its axis in approximately …………… | 24 hours |
| The Earth revolves around the Sun at a speed of …………… kilometers per second | 30 |
| The tilt of Earth's axis is responsible for the …………… length of days in different hemispheres at different times of the year | varying |
| A leap year has …………… days | 366 |
| The position of the Earth in its …………… affects which hemisphere is tilted towards the Sun | orbit |
| When the Northern Hemisphere experiences spring, the Southern Hemisphere experiences …………… | autumn |
| When the Northern Hemisphere experiences autumn, the Southern Hemisphere experiences …………… | spring |
| The concept of the …………… is fundamental to understanding both rotation and revolution | axis |
| The movement of the Earth that explains why the Sun appears to 'rise' and 'set' is actually the Earth's …………… | rotation |
