Observe this diagram of a plate boundary. Which statement BEST describes what is happening. It is that
the oceanic crust is being created.
the denser oceanic crust is subducting under the less dense oceanic crust

Which of the following best describes a natural hazard?
a natural event such as a hurricane or volcanic eruption which has the potential to cause social and economic impacts.
a natural event such as a hurricane or volcanic eruption which causes no harm.
a natural event such as a hurricane or volcanic eruption which causes social and economic impacts to a vulnerable population.
Which of the following best describes a natural disaster?
a natural event such as a hurricane or volcanic eruption which has the potential to cause social and economic impacts.
a natural event such as a hurricane or volcanic eruption which causes no harm.
a major hazard event that causes widespread disruption to a community or region, with significant impacts on people, the economy and/or the environment..
Why did the scientific community not believe Alfred's Wegener's theory of continental drift?
He did not have evidence to support his theory.
He could not explain what force was responsible for driving the plates apart.
He could not describe how the plates had drifted over time.
What is risk?
the conditions that increases the chances that a community will be impacted by a natural hazard.
the probability of a hazard event causing harming consequences (loss of life, injuries, damages)
major hazard event that causes widespread disruption to a community or region, with significant impacts on people, the economy and/or the environment.
the ability of individuals and societies to cope with the sudden impacts of disasters and restore to normal as quickly as possible.
