Humans have changed the landscape by cutting down trees / using too much coal and a result of this change is increase flooding / more crops produced by farmers in the area.

A little league baseball game in Grove City, Ohio, was canceled due to a severe thunderstorm. The storm brought high winds and a lot of precipitation to the city. The field was flooded and all roads in the city were shut down. Select two reasons why the flooding may have occurred.

Based on the evidence shown, what are some effects when a tsunami makes landfall? Select the three answers that apply.

occur.

An M6.2 earthquake struck a small town in California. Geologists and seismologists were able to warn people in advance, so no lives were lost. However, there was a lot of damage. The picture shows the aftermath of the earthquake.

Choose the words to finish the sentence.

An M6.2 earthquake is a very serious earthquake / happens all the time and people do not feel it.  These types of earthquakes are likely to cause roads to crumble and buildings to fall / small tremors.

What can the farmer do to reduce the impact of future flooding? Select  the two that apply.

List the events leading up to the volcano eruption likely occurred in order from first to last.

Read about what happened to the city after the volcanic eruption. As you read, Circle three long-term effects the volcanic eruption will have on the city.

The volcanic eruption produced a lot of lava. When the lava cooled, it formed rock, which can only be removed by blasting. The volcanic eruption also produced ash and debris. The ash and debris lay several meters deep over large areas of the city and prevented plants from growing. Much of the city became uninhabitable. It could take several years for vegetation to grow back in and around the city.

What is a volcano?

Which theory helped scientists understand how and where volcanoes erupt?

Volcanoes under the ocean are________

It is caused by the breakage of rocks due to changing pressure and tension built up by the injection of magma.

This movement caused the rocks to move past each other.

These are frequent vibrations that is caused by continuous resonance in the rocks brought about by upward movement of magma and gases to the surface.
