Quarter I Periodical Test in Science 10

It is the pieces of land that slowly and constantly moving?

• Faults

• Plates

• Cracks

• Crater

Which is a type of crustal plate that is thicker but less dense than the other crustal plate?

• Oceanic plate

• Continental plate

• Major plate

How will you compare the location of majority of earthquake epicenter with the location of volcanoes around the world?

• Earthquake epicenters are far from the location of volcanoes.

• There are no volcanoes on the majority of earthquake epicenter.

• Earthquake epicenters and volcanoes are both situated at the same location.

• They are not necessarily relevant.

Why does the oceanic crust sink beneath the continental crust at the subduction zone?

• the continental crust has a denser composition.

• the oceanic crust has the greater density

• The oceanic crust is pushed from the ridge

• The oceanic crust is pulled downward by Earth's magnetic field

What do you think is the importance of determining the epicenter of an earthquake?

• To prepare possible occurrence of earthquakes.

• To identify areas that are prone to earthquakes.

• have an awareness about the phenomena

• All of the above.

As the plate continues to grind against each other, what other geologic events could take place?

• earthquakes

• volcanic eruptions

• tsunamis

• meteor shower

What kind of plate boundary is shown in this picture?

• convergent

• divergent

• transform fault

• a and c

When geologists determined the age of the volcanic island through radiometric dating, their findings tell that:

• volcano near the magma plume is older

• volcano on the plume stays the same

• volcano far from the plume is younger

• volcano that is far the plume is older

How will you differentiate the thickness of the Earth?

• crust is the thickest

• core is the thicker

• mantle is thick

• crust is thinnest

If an earthquake begins, while you are in a building, which among the choices below is the safest thing for you to do?

• Call home

• Get under the strongest table, chair or other piece of furniture.

• Duck near a wall

• Lie flat on the floor and cover your head with your hands
