1. Which observation supported Wegener’s theory of continental drift?
<span>d. (The earth’s rotation could provide enough force to move the continents apart. )
</span>But this is not true. we know today that continents are present on the surface massive slabs called tectonic plates.
2. Which feature do you usually see when tectonic plates move apart?
b. <span>earthquakes
</span>
3. What happens in a convection cell?
b. Cold, dense material moves horizontally, while hot, less dense material moves vertically.
I believe we probably could if we use a cleaner source of energy such as solar power. It's renewable and almost unlimited.
Hope this helps you! :D
Answer:
d) a wall that was built as a boundary but is no longer considered a boundary
Explanation:
Take the Berlin Wall for example, it is a relic boundary because it no longer splits Germany into East and West Germany.
The definition for a relic boundary is a boundary that no longer exists as a boundary just a cultural landscape.
Answer:
through glacial deposits and ice cores
Explanation:
Scientists use ice to study ancient climates through glacial deposits and ice cores.
These two sources are fundamental to the study of ancient climates whose salient information has been preserved and locked in time through glacial deposits.
- A place can remain frozen for an extended period of time.
- Some gas bubbles can be trapped in the midst of ice being formed.
- These bubbles and compacting sequences of ice layers are used to interpret ancient climates.
- Ice cores are drilled an collected in barrels where they are taken to the laboratory for further studies.
- It is possible to even date each ice layer.
So, the solution is through glacial deposits and ice cores.
