Answer:
The inner core is the Earth's "interior".
P-waves pass through both the mantle and core, but are slowed and refracted at the mantle / core boundary. Whereas, S-waves pass from the mantle to the core and are absorbed due to shear waves being incapable of transmitting through liquids. Therefore, this is (further) proof the outer core does not behave like a solid substance.

Answer:
Have you ever seen a "shooting star" race across the sky at night? Shooting stars are meteors zooming at high speed through Earth's atmosphere and burning up along the way from friction. And right now is one of the best times to see them in person. The Perseids, which are impressive meteor showers that happen each year from mid-July to late August, have their peak activity around August 11 to 14. They're caused by Earth traveling through debris from the Comet Swift-Tuttle. Luckily, most meteors are tiny and burn up before hitting the ground. But if a meteor doesn't disintegrate, what's its impact on Earth? In this activity you'll explore how a meteorite’s size is related to the size of the crater it makes on impact..
