The Earth is not tilted "towards the sun".
The Earth's axis always points toward the same point in the sky, and that point
is quite near the star Polaris. It so happens that by pointing in that particular
direction, the Earth's axis is not parallel to the sun's axis, and the two of them
point in different directions by about 22.4 degrees.
That means that when the Earth is on one side of its orbit around the sun, the
Earth's north pole tilts toward the sun and its south pole tilts away.
Then, six months later, when we're halfway around our orbit and directly on the
other side of it, Earth's axis is pointing in exactly the same direction, but over on
this side that means that the north pole is now tilted away from the sun and the
south pole is tilted towards it.
if there was no tilt we would not have any seasons because no part of earth would be tilted toward the sun.:))))))
The angle of the earth's tilt from the sun causes the Earth's seasons.
The Earth tilts toward the sun at an angle of 23.44 degrees, because the Earth rotates, the entire Earth tilts toward the sun during summer and away from the sun during winter.
fall or spring
The earth has three motions around the sun. One is a wobble like a top. One is a change in the tilt angle. And one is the fact that the earth does not orbit the sun but it orbits the center of gravity of the solar system. When the earth has both the minimum tilt angle and the wobble is such that the closest distance to the sun in the northern hemisphere occurs in summer, an ice age occurs. When the earth has maximum tilt angle and the northern hemisphere was closest to the sun in winter, the ice ages end.
The Earth tilts at 23.5 degrees and when it is on one side of the Sun the tilt is toward the Sun. If it tilts toward the Sun then it has direct sunlight making it hot. On the other side of the Sun it tilts away causing indirect sunlight making it colder.
rotation of earth -earth is at a tilt so sometimes some parts get more sun then others rotation around the sun -earth will be at different distances from the sun as it rotates around
The earth tilt toward the sun
it is caused by the tilt of the earth axis.The Earth is tilted by 23.5C angle. So when the North was nearer to the Sun (and the South farther to the Sun) the North have Summer(and the South have Winter).
Tilt Angle
Around that time, earth's north pole is tilted toward the sun. This is also around the time that the earth is farthest from the sun.
It is due to different angle sunlight shine on different part of earth. The Heat gain to earth is from the Sun and loss to space. Sunlight reach earth at different angle and it is peak at the equator. On North and South pole, the sunlight reach surface at very narrow angle and the sunlight per surface area is a lot lesser that on the equator. While heat gain is uneven but heat loss is even that is colder climate at north and south and hotter climate at equator. In addition, earth rotate around the axis that is slightly tilt. It yield summer on northern hemisphere when it tilt down toward sun (sunlight reach at right angle) and winter when it tilt away from sun (sunlight reach at steep angle). Important to note: hotter and colder climate is not about the distance of the sun but angle that sunlight shine on earth.
