Answer;
True.
When the northern part of the earth is farthest away from the sun it gets cold and the other side of the earth gets warm / summer
Explanation;
The Earth's orbit is not a perfect circle, but a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away.
When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, because the Earth is tilted on its axis.
