Which of the following statements does NOT describe the process that occurs between the  

              convergence of two oceanic plates?      

• Two oceanic plates are moving towards each other.

• The younger oceanic plate undergoes subduction process.

• Subducting plate melts as it reaches the asthenosphere.

• As the two plates converge, continuous grinding on their leading edge is observe causing               earthquake to take place.

When two oceanic plates converge continuously for thousands of years, what will happen to the island arc?The islands will disappear.

• The islands will sink in water.

• The islands will increase in number and dimensions.

• The islands will be disintegrated by the pressure of water.

If Australia is moving about 2cm/ year and was drifted from the ridge by 1000km, how long ago was it

                  when Australia was near the ridge?

• 50 million years                                                   

• 10 million years                                                   

• 500 million years

• cannot be predicted

Arrange the following steps in the correct sequence to effectively prepare for a disaster:

1.  Store emergency supplies like food, water, and first aid kits.

2. Identify potential hazards in your area.

3. Create a family emergency communication plan.

4. Stay informed through official alerts and warnings.

• 2 → 3 → 1 → 4

• 1 → 2 → 3 → 4

• 2 → 1 → 3 → 4

• 3 → 2 → 1 → 4

Two converging oceanic plates can form___________

_______ are formed at divergent boundaries.

Scientists use seismic waves to study the Earth's interior and have discovered that each layer has  physical and chemical properties. By analyzing how these waves travel through the Earth, which of the following conclusions best explains the differences between the Earth's internal layers?

• The crust is the hottest and densest layer, allowing seismic waves to travel fastest.

• The mantle is solid but behaves plastically, allowing slow convection currents that drive plate movement.

• The outer core is solid and reflects seismic waves, preventing them from reaching the inner core.

• The inner core is liquid and generates Earth's magnetic field through convection.

How does the movement of tectonic plates contribute to the formation of mountain ranges?

• By pushing continental plates together, leading to uplift.

• By causing oceanic plates to sink into the mantle.

• By separating land masses and creating rift valleys.

• By creating volcanic activity that builds up land.

Hot molten materials in a convection cell rises near the ______________.

• outer core  

• crust 

• inner core 

• mantle

How will you relate the distributions of mountain ranges, earthquake epicenter, and volcanoes?

• Mountain ranges are found in places between where volcanoes and earthquake epicenters are

       also situated.

• Mountain ranges are found in places where volcanoes and/or earthquake epicenters are also

       situated.

• Mountain ranges are found only in places where earthquake epicenters are situated.

• Mountain ranges are found only in places where volcanoes are situated.
