Question

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
Select Answer
and do not move with tectonic plates. They are responsible for the creation of
Select Answer
island chains.

Answer 1

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.

Answer 2

first is wrong

Answer 3

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!

Answer 4

Describe how plant fossils found at Svalbard in Norway gave evidence of drifting continents.(1 point)
Responses

They were found only in that one location.
They were found only in that one location.

They were plants that became extinct millions of years earlier.
They were plants that became extinct millions of years earlier.

They were warm climate plants that would not grow in a cold polar area.
They were warm climate plants that would not grow in a cold polar area.

They were found in glacial deposits.

Answer 5

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.

Answer 6

Geologists found fossils of similar marsupials from the same time period across South America, Africa, Antarctica, India and Australia. What theory is supported by this discovery?(1 point)
Responses

Early marsupials were strong swimmers.
Early marsupials were strong swimmers.

The processes happening today are the same processes that have occurred in the past.
The processes happening today are the same processes that have occurred in the past.

Those continents were once a part of one supercontinent.
Those continents were once a part of one supercontinent.

A vast land bridge once connected those continents.

Answer 7

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.

Answer 8

How were the Himalayas formed?

(1 point)
Responses

when a mid-ocean ridge split apart
when a mid-ocean ridge split apart

when two plates collided with each other
when two plates collided with each other

due to a sudden shift along a transform boundary
due to a sudden shift along a transform boundary

due to an increase in volcanic activity

Answer 9

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.
