The correct answers for your fill-in-the-blank statements are:
1. **stationary**
2. **volcanic**
So the completed sentences would read:
Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of hotspots, where the magma is much hotter than the surrounding magma. These are **stationary** and do not move with tectonic plates. They are responsible for the creation of **volcanic** island chains.

I apologize for the oversight. The correct term to complete the first blank is **"fixed."**
So the completed sentences would read:
Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of hotspots, where the magma is much hotter than the surrounding magma. These are **fixed** and do not move with tectonic plates. They are responsible for the creation of **volcanic** island chains.
Thank you for your patience!

The correct response is:
**They were warm climate plants that would not grow in a cold polar area.**
This finding indicates that Svalbard, which is currently a cold polar region, was once located in a much warmer climate, supporting the idea of continental drift where continents have moved to their current positions over millions of years.

The correct response is:
**Those continents were once a part of one supercontinent.**
This discovery supports the theory of continental drift, suggesting that the continents were once connected, allowing for the widespread distribution of similar marsupial fossils across these now separate landmasses.

The correct response is:
**when two plates collided with each other.**
The Himalayas were formed as a result of the collision between the Indian Plate and the Eurasian Plate, which began around 50 million years ago and continues to this day, causing the mountains to rise.
