Step 1
Which row correctly lists the three parts of the Earth in order of their distance from its centre?
Answer
The correct order is: D outer core, mantle, crust. This sequence is based on the distance from the Earth's center, with the outer core being the furthest, followed by the mantle, and finally the crust, which is nearest to the surface.
Step 2
Explain why it is difficult to predict when a tsunami will occur.
Answer
Tsunamis are caused by {earthquakes/volcanoes}, which themselves are unpredictable. The movement or slipping of tectonic plates can trigger tsunamis, but such geological events often happen without warning. Additionally, they can result from landslides or even meteorite impacts. Thus, the sudden jolt or slip can occur randomly and at any time, making it inherently challenging to forecast tsunami occurrences.
