The appropriate answer is a. the temperature is high enough but pressure low enough to melt iron. The earth's core is composed of two layers; the inner and outer core. Both layers are composed mainly of iron and nickel. The main difference between the two layers is that the inner core is solid and the outer core is liquid. The inner core is solid because of the pressure created by the overlaying layers; the outer core, mantle and the crust. The inner core is however hotter than the outer core.

Mamont248 [21]
Most of our planet would rapidly become very inhospitable. Half of the planet would almost continuously face the heat of the Sun, while half would face the cold of space. Life could continue in a narrow twilight zone between the hot and cold halves.

How does the tilt of Earth’s axis and its movement around the sun play a part in the changing of the seasons in the Northern Hem
Vinil7 [7]

The Earth's tilt is causing change of seasons on the latitudes north and south from 23 degrees, mostly being manifested in four different seasons.

Explanation:

The tilt of the Earth is a major factor that contributes to the occurrence of seasons in some parts of the planet. The tilt is roughly 23 degrees, and it half of the year it makes the Northern Hemisphere to be more exposed to the Sun, while in other half of the year it makes the Southern Hemisphere to be more exposed to the Sun. This results in changes of seasons throughout the year.

When the Northern Hemisphere is tilted toward the Sun, it experiences summer. During the summer, the North Pole experiences constant daylight because it is constantly exposed to sunlight. When the Northern Hemisphere is tilted away from the Sun, then it experiences winter, and the North Pole has constant night because it is to exposed to the Sun at all.

The transitional period between the winter and the summer is the spring, where the sunlight and temperatures gradually increase. The transitional period between the summer and the winter is the autumn, where the sunlight and temperatures gradually decrease. This is the same on the Southern Hemisphere as well, just in the opposite part of the year.

There are four stages that mark the seasons:

  • spring equinox
  • summer solstice
  • autumn equinox
  • winter solstice
