1. The Earth
The Earth is the planet where we live. To study it, we use two
imaginary lines:
The axis crosses Earth through the centre and passes through the two
poles: the North Pole and the South Pole.
The equator divides Earth into two halves called the hemispheres: the
Northern Hemisphere and the Southern Hemisphere.
The Earth makes two types of movements: rotation (it rotates on its
axis) and revolution (it revolves or orbits around the Sun).
Thanks to rotation, we have day time and night time. Thanks to the
revolution, we have four different seasons: spring, summer, autumn
(fall) and winter.
