First, the Earth's tilt DOES NOT change; the Earth spins like a gyroscope, and is remarkably stable. However, the Earth's axis, fixed as it is, is not perpendicular to the plane of the Earth's orbit. As the Earth orbits the Sun with its unchanging "tilt", the Sun "appears to" move north of the equator in late March, and move south of the equator in late September.
So starting on March 21, the Earth's axis is tilted (just a bit) toward the Sun, giving us longer and longer days until June 21. At the equator, it doesn't really make any difference, but for higher latitudes, the day length can become quite long.
The longest season on the northern hemisphere is summer.
WHEN TH SUN TILTS TOWARD THE SOUTHERNHEMISPERE IT GIVES YOU WINTERAnswer 2:Actually the sun does not tilt.The earth axis does, though.
The northern hemisphere has much more land than the southern hemisphere.
Because Earths axis isn't in alignment with the sun's axis. Rather it is tilted, so during part of the earths orbit around the sun, the northern hemisphere receives sunlight that is more nearly perpendicular to the earths surface. Then when Earth is on the exact opposite side of the sun the opposite applies. Earths rotation around the sun is completely independent of its daily rotation, so its North to South axis remains in a completely fixed position during its entire rotational cycle. (There is a significant wobble, but it has a period of 26,000 years).
WinterWhen the north end of the earths axis is tilted toward the sun, the northern hemisphere has summer. At the same time, the south end of earths axis is tilted away from the sun. As a result the southerns hemisphere has winter.

Between March 20th and September 20th (or there abouts) the northern hemisphere receives the majority of the sunlight, while during September 20th to March 20th, the southern hemisphere receives more light. This is due to the earths tilt.
To the north of the equator is the northern hemisphere, and to the south is the southern hemisphere.

because of the Earths rotation the ocean currents are not in straight lines. In the northern hemisphere they curve to the right
