Downcutting speed is determined by the base level of the stream. It is the lowermost point that a valley or streams can lose.</span>
If the Earth's rotation axis were tilted by 45 degrees instead of 23.5 degrees, then the seasons would be more extreme.
<h3>What is the rotation axis of Earth?</h3>
The rotation axis of the Earth is an imaginary straight line around which the Earth spins. It goes from the North Pole to the South Pole cutting through the center of the Earth. The axial tilt of the Earth which is also known as the obliquity of the ecliptic is about 23.5 degrees. Due to this tilt, the Sun shines on different latitudes and longitudes at different angles throughout the year. This is why we have different seasons. Uranus has the largest axial tilt in the solar system, which is around 98 degrees.
If the Earth's rotation axis were tilted by 45 degrees instead of 23.5 degrees, then the seasons would be more extreme as the rays of the Sun would fall directly in the summer and not so direct in the winter.
