What’s the Summer season Solstice? – Science questions for youths

The summer season solstice is the longest day of the yr when the north pole of the earth is closest to the solar. There are two solstices a yr. One in June and one in December. The time of the solstice is identical in all places on the planet, however the season is determined by the place you might be on Earth (northern or southern hemisphere).

The time period solstice consists of the Latin Sol which means the solarand cease which implies stand nonetheless

Within the Northern Hemisphere, the June solstice is the primary day of summer season and the December solstice the primary day of winter. Within the southern hemisphere it’s the different method round.

It’s because the earth is tilted. Half of the Earth tilted in the direction of the solar is in summer season and that a part of the Earth tilted away from the solar is in winter. You possibly can see within the picture under that every hemisphere of the Earth is tilted towards the solar one half of the yr and away from the solar the opposite half of the yr.
