• Question 1 of 5 1. Question Consider the following statements. Along much of the Pacific Ring of Fire, tectonic plates move towards each other creating subduction zones. Subduction zones are also where most of the violent earthquakes on the planet occur. In the past 50 years, the Indian Plate has been stable and has not seen any subduction. Which of the above statements is/are correct? a) 1, 2 b) 1 only c) 1, 3 d) 1, 2, 3 Correct Solution: a) Along much of the Ring of Fire, tectonic plates move towards each other creating subduction zones. One plate gets pushed down or is subducted by the other plate. This is a very slow process – a movement of just one or two inches per year. As this subduction happens, rocks melt, become magma and move to Earth’s surface and cause volcanic activity. Subduction zones are also where most of the violent earthquakes on the planet occur. The December 26, 2004 earthquake occurred along the subduction zone where the Indian Plate was subducted beneath the Burma plate. Incorrect Solution: a) Along much of the Ring of Fire, tectonic plates move towards each other creating subduction zones. One plate gets pushed down or is subducted by the other plate. This is a very slow process – a movement of just one or two inches per year. As this subduction happens, rocks melt, become magma and move to Earth’s surface and cause volcanic activity.

#### 1. Question

Consider the following statements.

• Along much of the Pacific Ring of Fire, tectonic plates move towards each other creating subduction zones.

• Subduction zones are also where most of the violent earthquakes on the planet occur.

• In the past 50 years, the Indian Plate has been stable and has not seen any subduction.

Which of the above statements is/are correct?

• d) 1, 2, 3

Solution: a)

Along much of the Ring of Fire, tectonic plates move towards each other creating subduction zones. One plate gets pushed down or is subducted by the other plate. This is a very slow process – a movement of just one or two inches per year. As this subduction happens, rocks melt, become magma and move to Earth’s surface and cause volcanic activity.

Subduction zones are also where most of the violent earthquakes on the planet occur. The December 26, 2004 earthquake occurred along the subduction zone where the Indian Plate was subducted beneath the Burma plate.

• Question 2 of 5 2. Question Which of the following regions of the world is/are seismically active? Mid-Atlantic Ridges Alpine-Himalayan belt Central Africa Select the correct answer code: a) 1, 2 b) 1, 2, 3 c) 1, 3 d) 1 only Correct Solution: a) Seismic belt, narrow geographic zone on the Earth’s surface along which most earthquake activity occurs. The two major seismic belts are the Circum-Pacific Belt, which surrounds the Pacific Ocean, and the Alpine-Himalayan orogenic belt, which stretches from the Azores through the Mediterranean and Middle East to the Himalayas and Indonesia, where it joins the Circum-Pacific Belt. A purely oceanic seismic belt lies along the mid-Atlantic ridge. Seismicity of West and Central Africa is low to moderate, as is normal with stable continental interiors.
