Which event below is the most difficult to forecast because they often happen without warning?

Which of these steps would help to reduce the chances of a mudslide occurring in a hilly region?

when a tectonic plate moves it can produce

extreme weather events such as floods, hurricanes, and tornadoes; classified by the extent and intensity of their impact on the ecosystem

forces resulting from processes occurring within Earth’s crust

waves of energy that travel through Earth and are the result of an earthquake, volcano, or explosion

major geological event that occurs when plates shift suddenly and release stored energy; a frequent occurrence along all types of plate boundaries

vent in which molten rock spews out of the mantle to the surface of the earth as ash, lava, and gases

a giant wave usually caused by an earthquake or volcano beneath the ocean floor

the sudden movement of rock and soil down a slope

a rising body of water that submerges normally dry land

a severe storm that develops over tropical oceans and whose strong winds of more than 120 km/h spiral in toward the intensely low-pressure storm center

rapidly whirling, funnel-shaped cloud that reaches down to touch Earth’s surface

a large fire that spread quickly over a natural area

events in nature that may have a negative effect

Which of the following is NOT a natural hazard?

Geoscience Processes

Geoscience processes are natural actions that change the Earth's surface over time. These include things like erosion, weathering, earthquakes, and volcanoes. For example, rivers can slowly wear away rocks and soil, carving deep valleys or canyons. Wind can carry sand and shape deserts, while glaciers can move across land, leaving behind deep grooves and valleys. 

Some geoscience processes happen slowly, over millions of years, like mountains forming or rocks breaking down into soil. Others, like earthquakes and volcanic eruptions, happen quickly and can cause big changes in just a few minutes or days. 

These processes show how the Earth is always changing, even if it happens so slowly that we don’t notice it every day.

Predicting Natural Disasters

The best way to predict or tell when natural disasters will occur is to study ones that have already happened. This gives scientists important information about the events that lead up to disasters. It also helps the scientists understand the forces of nature that cause the disasters. 

Scientists have developed a good understanding of the factors that lead to hurricanes, tornadoes, and flooding. Predicting events such as earthquakes and volcanic eruptions, however, is much more difficult. Volcanoes may give warning signs, such as leaking gases or spouting lava, before erupting, but sometimes they erupt with no warning at all. 

Earthquakes are also difficult to predict. However, scientists are aware of the regions in the world where earthquakes are most likely to occur. In these places they use equipment to monitor any changes that might suggest an earthquake is about to happen. 

Refer to “Predicting Natural Disasters”. Which of the following best describes the relationship between earthquake and volcano locations?
