1.
Name the three type of plate boundary.
Correct Answer
A. Convergent, Divergent, Transform
Explanation
The correct answer is Convergent, Divergent, Transform. These are the three types of plate boundaries. Convergent boundaries occur when two plates collide, causing one plate to be forced beneath the other, forming a subduction zone. Divergent boundaries happen when two plates move away from each other, creating a gap that is filled with new crust material. Transform boundaries occur when two plates slide past each other horizontally, causing intense earthquakes. These three types of plate boundaries play a crucial role in shaping the Earth's surface and are responsible for various geological phenomena such as mountain formation, volcanic activity, and earthquakes.
2.
Name the type of fault that is most like a divergent boundary.
Correct Answer
C. Normal
Explanation
A normal fault is most like a divergent boundary because both involve the pulling apart of tectonic plates. In a divergent boundary, the plates move away from each other, creating a gap. Similarly, in a normal fault, the hanging wall moves downward relative to the footwall, creating a gap. Both processes involve tensional stress and result in the extension of the Earth's crust. Therefore, a normal fault is the type of fault that is most similar to a divergent boundary.
3.
Tension and Compression can be described as?
Correct Answer
D. Tension is like stretching something while compression is like squeezing it.
4.
A strike slip fault is like a ?
Correct Answer
B. Transform Boundary
Explanation
A strike-slip fault is like a transform boundary because it is characterized by horizontal movement where two tectonic plates slide past each other in opposite directions. This type of boundary does not involve the plates colliding or separating, but rather, the plates grind against each other, causing earthquakes. Transform boundaries are commonly found along the boundaries of the Earth's tectonic plates, such as the San Andreas Fault in California.
5.
If I see folded mountains, I am probably near a _________________ boundary.
Correct Answer
A. Convergent
Explanation
Folded mountains are formed when two tectonic plates collide and push against each other, causing the crust to buckle and fold. This type of plate boundary is known as a convergent boundary, where two plates are moving towards each other. The collision results in the formation of folded mountains, such as the Himalayas or the Alps. Therefore, if someone sees folded mountains, it is likely that they are near a convergent plate boundary.
6.
The folded mountains in question 7 were created when a ______________ plate collided with a ______________ plate.
Correct Answer
C. Continental, Continental
Explanation
The folded mountains in question 7 were created when two continental plates collided. This collision caused the rocks and sediments at the edges of the plates to buckle and fold, forming mountain ranges. Continental plates are composed of less dense, thicker crust compared to oceanic plates, which makes them more likely to fold and create mountains when they collide.
7.
Landforms that show evidence for Divergent boundaries are _________________.
Correct Answer
A. Rift Valleys and Mid-Ocean Ridges
Explanation
Divergent boundaries occur when two tectonic plates move away from each other, creating new crust. Rift valleys are formed on land when the Earth's crust stretches and thins, causing the land to sink and form a valley. Mid-ocean ridges are underwater mountain ranges that form as magma rises to the surface and creates new crust. Both rift valleys and mid-ocean ridges are evidence of divergent boundaries, where the Earth's crust is pulling apart. Folded mountains and volcanoes, on the other hand, are formed by convergent boundaries where two plates collide. Plateaus and canyons can be formed by various geological processes and are not specifically associated with divergent boundaries.
8.
Tension creates
Correct Answer
A. Normal Faults
Explanation
Tension is a type of stress that pulls apart the Earth's crust. Normal faults occur when the hanging wall moves downward relative to the footwall due to tensional forces. This movement creates a gap or space between the two blocks of rock, resulting in a fault. Therefore, it can be inferred that tension creates normal faults.
9.
Compression creates ________________.
Correct Answer
B. Reverse faults
Explanation
Compression creates reverse faults. Reverse faults occur when two blocks of rock are forced together by compressional forces, causing one block to move upward relative to the other. This type of faulting is commonly associated with convergent plate boundaries, where tectonic plates collide and compress against each other. The compression causes the rocks to deform and fracture, resulting in a reverse fault.
10.
Convection currents in the mantle _____________________ .
Correct Answer
C. Make the continental plates move
Explanation
Convection currents in the mantle refer to the movement of molten rock in the Earth's mantle. These currents are caused by the transfer of heat from the Earth's core to the surface. As the molten rock heats up, it becomes less dense and rises towards the surface, while the cooler rock sinks back down. This continuous cycle of rising and sinking creates a circular motion, which in turn exerts a force on the overlying continental plates. This force causes the plates to move, leading to phenomena such as earthquakes, volcanic activity, and the formation of mountains.
