SCIENCE 6 - FINAL EXAM REVIEW

Alfred Wegener is the scientist who proposed the Continental Drift Theory in the early 1900s which states that all continents originated from one supercontinent called Pangaea that split and drifted over time. He provided a lot of evidence so that his fellow scientists would believe in him. Which of the following evidence was NOT provided to support his theory?

• weather conditions of each continental region

• fossils found in the different continents

• similarities in the rock layers

• fit of the continents

Which of the following will most likely happen in the Earth’s crust as a result of the movement shown in the image given?

• A ridge will be formed.

• Frequent volcanic eruptions might occur.

• A chain of mountain ranges will be formed.

• The thickening of landmasses will be noticeable.

Which of the following BEST describes the change in the Earth’s surface as caused by a continental-to-continental convergent plate boundary?

• A denser plate is pushed downward forming a chain of active volcanoes.

• Plates will collide and break apart after some time and will trigger the seafloor spreading.

• Landmasses will be buckled upward forming mountain ranges like the Himalayan Ranges between Asia and India.

• A plate will be consumed back into the lithosphere forming large deep trenches like the Marianas Trench in the Western Pacific Ocean.

When two colliding oceanic plates causes some changes when it moves, which of the following will most likely to be formed?

• ridges

• valleys

• mountain ranges

• chains of active volcanoes

The West Valley Fault is one of the active faults in the Philippines. Once this fault moves, it causes an earthquake. What type of plate boundary is illustrated by this fault?

• convergent

• divergent

• transform

• transform

How will a seismologist measure the damage to the Earth’s surface if an earthquake occurs?

• be getting its magnitude

• be using a Ritcher scale

• by using a Modified Mercalli scale

• by using a hygrometer and a barometer

What will be the effect of Southwest Monsoon on the Philippines?

• cold wind but little rain

• warm wind and dry season

• warm wind and moderate rains

• heavy rains and severe flooding

Which of the following is most likely to happen if the Northeast and Southwest trade winds come together?

• There will be formation of sea breeze.

• There will be formation of land breeze.

• There will be formation of monsoon winds.

• There will be formation of band of clouds which can cause rains due to ITCZ.

Stationary front occurs when a boundary between air masses stops advancing. What will happen if a region/place has a stationary front?

• The place will experience steady rains.

• The place will experience light rains and winds.

• The place will experience moderate winds and strong rains.

• There will be no effect in the region/place that has a stationary front.

In which position of the Earth will the southern hemisphere experience autumnal/fall equinox?

• position A

• position B

• position C

• position D
