i thought it was because the Earth orbits the Sun in an oval rather than a circle and summer was when we were closest to it, but since its summer south of the equater now that can't be it, so is it the tilt of the Earth that causes it or something else?

Actually, that is not true. In terns of distance, we are actually closest to the sun in our winter (northern hemisphere). June 21st, we are the farthest away from the sun- but we are tilted toward the sun the most. It is the angle of the sun. Proof: If it was the disance, then wouldn't the entire planet have summer and winter at the same time?

The tilt of the earth's axis and the earth's revolution around the sun both contribute to the formation of summer and winter seasons.
If the tilt only is there and there is no revolution,the earth will always be in a particular direction from the sun and only one hemisphere will always be pointing towards the sun.So, that hemisphere will always be having summer season and the other hemisphere always will have winter season.
On the other hand ,if the the tilt is not there and only the revolution alone is there, the day time and the night time will always be the same in all places throughout the year and again there will be no seasons anywhere in the world.

Summer and winter are caused by the tilt of the Earth. The Earth is closest to the Sun in the northern hemisphere winter when the axis of the earth (north pole) points away from the Sun. In the northern hemisphere summer the north pole points toward the Sun and therefore more energy is received per unit area of earth surface in the NH at this time of year.

it is indeed the tilt of our axis which causes the seasons. the earth as is rotates travels around the sun and in winter the north pole will be tilted away from the sun and when the earth is on the other side of the sun in summer the north pole is tilted toward the sun

The earth axis is quite a few levels off of a line perpendicular to the elliptic. At Earth's closest factor to the sunlight, the northern hemisphere is tilted up, and faraway from the elliptic aircraft. that provides us a cooler summer than the southern hemisphere. i think of...
