Annual meteor showers occur when the Earth passes through the orbital path of acomet. The intensity of these showers vary from year to year. Which of the following may bethe reason for this?
Group of answer choices
- Meteor showers are not caused by comet debris
- Sun's temperature
- en distribution of debris along comet's orbit
- Earth's rotation axis
Differentiate between an gas tail and dust tail of a comet.

typical meteorite is 11 times smaller than the
diameter of the crater, what was the diameter (in
km) of the original meteorite?
km
What is the estimated depth (in km) of the crater if
its depth is one-ninth its diameter?
km
