The Stones
Description
תהליכים גיאולוגיים מורכבים יוצרים את שלושת סוגי הסלעים העיקריים: סלעי יסוד, סלעי משקע וסלעים מטמורפיים. הסקירה מציגה כיצד כוחות של חום, לחץ ושחיקה משנים את החומר לאורך מיליוני שנים ומניעים את מחזור הסלעים הבלתי פוסק בכדור הארץ.

Daniel Asks: What is a Falling Star
Credit: מכון דוידסון לחינוך מדעיDiscover the spectacular phenomenon of the "shooting star," which is not a star at all, but rather a tiny particle of dust or space rock entering Earth's atmosphere at breakneck speeds. This video explains how friction with the air generates immense heat and the shimmering trail of light we see in the night sky. It also provides a simple and fascinating breakdown of the differences between a meteoroid, a meteor, and a meteorite.3:18

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
