The Moon |
Card: 18 / 30 |
|
|
What suggests that tectonic plates are constantly shifting? |
Card: 19 / 30 |
|
|
The observation of earthquakes and volcanoes at plate boundaries, the jigsaw-like fit of continental coastlines, and the presence of similar fossils on widely separated continents suggest that tectonic plates are constantly shifting. |
Card: 20 / 30 |
|
|
Which process explains how the Moon was formed according to the collision theory? A) Cosmic Expansion B) Earth Impact C) Stellar Formation D) Nebula Formation |
Card: 21 / 30 |
|
|
B) Earth Impact |
Card: 22 / 30 |
|
|
Fill in the blank: Nebulae are primarily made up of ______ and helium. |
Card: 23 / 30 |
|
|
Hydrogen |
Card: 24 / 30 |
|
|
True or False: The Earth's magnetic field has remained constant throughout its history. |
Card: 25 / 30 |
|
|
False. The Earth's magnetic field has undergone multiple reversals. |
Card: 26 / 30 |

|
Riddle: I’m a place where new stars are born, filled with gas and dust. What am I? |
Card: 27 / 30 |
|
|
A stellar nursery |
Card: 28 / 30 |
|
|
What evidence supports the theory of continental drift regarding the fit of coastlines? |
Card: 29 / 30 |
|
|
The coastlines of continents fit together like pieces of a jigsaw puzzle, and fossils of the same species, such as Mesosaurus and Glossopteris, found on widely separated continents suggest they were once connected. |
