Why does summer occur in the southern hemisphere when winter occurs in the northern hemisphere

summer for the southern hemisphere takes place during the months of December, January, and February because that is when it receives the most direct sunlight.

Explanation:

The earth is tilted in relation to its poles, leaving half of it closer to the sun than the other at any one time. When it's winter, it's because the spot where you live is facing away from the sun, meaning the other half is facing towards it, thus, they have summer.

In short, it's because of the tilt of the earth in relation to its poles.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
