Surface Features and Plate Boundaries

What is the Mid-Atlantic Ridge?

• A convergent plate boundary where tectonic plates collide.

• A divergent plate boundary where new oceanic crust is formed.

• A transform fault where plates slide past each other.

• An underwater mountain range formed by volcanic activity.

What is the difference between oceanic and continental crust?

• Oceanic crust is thicker and less dense than continental crust.

• Oceanic crust is denser and thinner than continental crust.

• Oceanic crust and continental crust are identical in density and thickness.

• Oceanic crust is found only under the oceans, while continental crust is found only on land.

What is the relationship between tectonic plates and earthquakes?

• Earthquakes are caused by volcanic activity unrelated to tectonic plates.

• Earthquakes often occur at plate boundaries due to the movement and interaction of tectonic plates.

• Tectonic plates are not related to earthquakes in any way.

• Earthquakes only happen in the middle of tectonic plates.

What happens to the temperature of rocks as you move deeper into the Earth?

• The temperature of rocks decreases.

• The temperature of rocks remains constant.

• The temperature of rocks generally increases due to the geothermal gradient.

• The temperature of rocks fluctuates randomly.

What is a plate boundary?

• A region where two tectonic plates meet, leading to geological activity such as earthquakes, volcanic eruptions, and mountain building.

• A type of geological formation that occurs in the ocean.

• An area where tectonic plates are moving away from each other.

• A location where tectonic plates are stationary and do not interact.

What are the three main types of plate boundaries?

• Convergent, divergent, and transform boundaries

• Convergent, divergent, and subduction boundaries

• Transform, divergent, and collision boundaries

• Convergent, collision, and tectonic boundaries

What is the significance of the Pacific Plate's movement?

• It causes volcanic eruptions in the region.

• It affects geological features and seismic activity, including the formation of islands and earthquakes.

• It has no significant impact on the environment.

• It leads to the extinction of marine species.

What is the significance of Iceland's location?

• Iceland is located on the Mid-Atlantic Ridge, making it a unique area for studying plate tectonics and volcanic activity.

• Iceland is situated near the Arctic Circle, which influences its climate and biodiversity.

• Iceland is located on the equator, resulting in a tropical climate and diverse ecosystems.

• Iceland is positioned at the intersection of several major trade routes, enhancing its economic significance.

What geological features are commonly associated with transform plate boundaries?

• Volcanoes and lava flows

• Mountain ranges and ridges

• Faults and earthquakes

• Ocean trenches and subduction zones

What is the role of density in plate tectonics?

• Density determines the age of tectonic plates.

• Density affects the temperature of the Earth's crust.

• Density determines which plate subducts when two plates collide; the denser oceanic plate typically subducts beneath the less dense continental plate.

• Density has no effect on plate tectonics.
