How would seasons on Earth differ if Earth's axis was at a 90 degree angle relative to its orbit?
Triss [41]

Answer:

There would be no seasons anywhere on Earth

Explanation:

If the Earth's axis was not tilting and it was at a 90 degrees angle relative to its orbit, then the seasons on Earth would disappear. The climate on the planet would be defined by the latitude. The equator and the areas close to it would always have summer, as they will receive direct sunlight throughout all of the year. The mid-latitudes will always have temperate climate, reminding of spring and autumn, as the sunlight will not be very direct, but it will also not be very dispersed, jut enough to create a constantly pleasant climate. The higher latitudes will always have winter, as the sunlight will come at a very low angle throughout all of the year, thus it will be very dispersed, not enough to ever warm this parts enough, so they will constantly be under ice.

In landscapes dominated by low-infiltration capacity, what is the first step in erosion?
Oksana_A [137]
Low infiltration capacity means that the soil cannot absorb much water per volume. The first step in erosion in a landscape dominated by low-infiltration capacity is the raindrop splash. This is where raindrops displace the soil from their original place because the soil cannot absorb adequate amounts of water.
