Q1-REVIEWER IN SCIENCE 10

Imagine you are a marine geologist studying both oceanic and continental crust. You observe that the rocks present under the ocean are basalt, while the rocks present on the continents are composed mainly of granite. Based on your understanding, which statement BEST describes the type of crust likely present beneath the oceanic and continental crust?

• A. Continental and oceanic crusts have the same weigh.
• B. Oceanic crust is less dense than continental crust.
• C. Continental crust is thicker than oceanic crust.
• D. Oceanic crust is thicker than continental crust.

How will you relate the distributions of mountain ranges, earthquake epicenters, and volcanoes using the given figure below?

• A. Mountain ranges are found in places between where volcanoes and earthquake epicenters are also situated.
• B. Mountain ranges are found in places where volcanoes and/or earthquake epicenters are also situated.
• C. Mountain ranges are found only in places where earthquake epicenters are situated.
• D. Mountain ranges are found only in places where volcanoes are situated.

Which statement does best describe the location of the majority of earthquake epicenters relative to the location of volcanoes around the world?

• A. They are far adjacent.
• B. They are always 3 kilometers away from each other.
• C. They are situated at the same location.
• D. They are not necessarily relevant.

As a mountaineer, you notice the highest peak in a mountain range has slowly shifted eastward. What geological process is MOST LIKELY responsible for the formation of mountains?

• A. Erosion
• B. Plate Tectonics
• C. Volcanic Activity
• D. Deposition of Sediments

You are a geologist studying a region with a variety of landforms, including mountains, volcanoes, and deep ocean trenches. Which of the following is NOT a direct result of plate tectonics?

• A. The formation of mountain ranges
• B. The formation of deserts
• C. The creation of volcanoes
• D. The occurrence of earthquakes

If you are seismologist and you want to locate the epicenter of an earthquake, what will be the distance of Pampanga using the given data?

• A. 200km
• B. 400km
• C. 600km
• D. 1000km

Scientists are evaluating data from the Mid-Atlantic Ridge to determine the type of plate boundary. They observe: (1) new oceanic crust forming at the ridge axis; (2) frequent, relatively low-magnitude earthquakes; and (3) a central rift valley. Which conclusion ACCURATELY reflects the evidence?

• A. The Mid-Atlantic Ridge is a convergent boundary because plates are colliding.
• B. The Mid-Atlantic Ridge is a transform boundary because plates are sliding past each other.
• C. The Mid-Atlantic Ridge is a divergent boundary because plates are moving apart.
• D. The Mid-Atlantic Ridge is a subduction zone because one plate is sliding under another.

Which of the following are the three types of plate boundaries?

• A. Convergent, Divergent, and Transform Fault
• B. Trench, Mountains, and Volcanoes
• C. Convergent, Transform, and Convection
• D. Convergent, Divergent, and Trench

When plates slide pass each other, they formed ____________.

• A. Fault
• B. Mountain Ranges
• C. Mid-oceanic Ridges
• D. Volcano

You are a marine geologist studying the Mid-Atlantic Ridge, where a new ocean floor is being created. What is the primary geological process occurring at a divergent boundary?

• A. When plates move away from each other.
• B. When plates slide pass from each other.
• C. When plates move towards each other.
• D. When plates sink beneath from each other.
