Venus is similar to Earth in size and density. Most scientists also believe that its inner layers are similar to Earth's. Its inner core is most likely made up of charged metal particles, much like Earth's.
Earth, however, generates a dynamo in its core, which is responsible for its magnetic field. Venus, on the other hand, has
almost no magnetic field.
Based on what you know about Earth's composition and what generates its magnetic field, offer one explanation for why
Venus does not have a strong magnetic field,

here's your

hope it

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

the second type of galaxy is called a barred spiral, which has a thing called a bar straddling the nucleus
