Geologic Processes-2.2

Which of the following best describes the outer core?

• The outer core is the middle layer of Earth, and contains the most heat.

• The outer core is the outermost layer of Earth, and varies in temperature and thickness

• The outer core is a dense, solid layer, and is responsible for the motion of Earth's plates.

• The outer core is a liquid, and is responsible for Earth's magnetic field

500 years. The Mayon Volcano is located on a convergent oceanic-continental boundary which creates a subduction zone. Which option best explains how the interaction between these two plates are able to cause a volcanic eruption?

• The two equally dense tectonic plates separate, allowing magma from the crust to flow upward and out of the opening that formed between the two plates.

• The less dense oceanic crust is forced under the more dense continental crust, which causes the continental crust to heat up, melt and flow upward as magma.

• The two equally dense tectonic plates collide and both push upward, which causes friction to heat up and melt the crust between the two rising plates.

• The more dense oceanic crust is forced under the less dense continental crust, which causes the oceanic crust to heat up, melt and flow upward as magma.

Which option best explains how volcanoes are formed on Earth?

• Divergent plates cause mountains to separate, leaving room for magma to enter and erupt.

• Hot magma in the mantle convects, slowly moving as heat circulates from the core to the surface, pulling or pushing the tectonic plates.

• Water just under the crust heats the magma, moves from the mantle to the bottom of the crust, until pressure increases and it erupts.

• Weathering and erosion carve out an opening at the tops of mountains, which allows magma in the ground to rise and cause eruptions.

Which option describes how heat and the movement of Earth's tectonic plates contribute to the formation of an ocean basin?

• Heat from the mantle conducts through the tectonic plates causing the plates to converge and form ocean basins.

• Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.

• Heat from the mantle forms convection currents causing the plates to transform and form the ocean basins.

• Heat from the mantle conducts through tectonic plates causing them to melt to form ocean basins.

Which of the following correctly compares Earth’s inner core and mantle?

• The inner core is less dense than the mantle.

• The inner core is thinner than the mantle.

• The inner core is a liquid and the mantle is a solid.

• The inner core is closer to the crust than the mantle

A group of scientists are studying two tectonic plates. When they analyzed the data, they noticed that the two plates have been pushing against each other over the past ten years. What option below describes what will most likely occur between the two plates?

• The plates will slowly converge causing a mountain to form.

• The two plates will quickly transform causing the formation of a canyon.

• The two plates will quickly diverge forming an ocean basin.

• The two plates will slowly subduct causing an earthquake.

Heat generated by the core is passed to the mantle by conduction. Which option below best describes how the flow of heat through the mantle affects the movement of the Earth's tectonic plates?

• Heat is transferred from the mantle to the crust by radiation, which then causes the plates to move on the surface.

• Heated material in the mantle rises to the surface forming a heated cell, which causes the crust to harden and move the plates.

• Heated material in the mantle expands and rises towards the crust where it then cools, forming a convection current, which causes plate motion.

• Heat conducted from the Earth's mantle moves tectonic plates due to the gravitational pull from the Earth's core.

Two students are discussing the processes that form the different rocks near mountains and lakes. Which choice below compares the formation of rocks at these locations?

• Igneous rock is formed by volcanoes releasing magma from the mantle, the rock cools and piles up forming a mountain. Rivers direct water to cool magma underground forming metamorphic rock under lake beds.

• Metamorphic rock is formed by pressure and heat of tectonic plates is then pushed up as mountains form. Rivers deliver weathered rocks into lake beds forming sedimentary rock as more layers are added.

• Sedimentary rock is formed from the heat and pressure in between tectonic plates to form mountains. Rivers deliver weathered rock to lake beds and form igneous rock over long periods of time.

• Mountains push weathered rocks underneath tectonic plates to form sedimentary rocks inside the mantle. Rivers erode igneous rocks over time to form metamorphic rock.

What are the benefits and limitations of a rock cycle diagram without images of different type of rocks but shows the names and processes?

• The model includes types of rocks but does not give a visual representation of the rocks.

• The model includes the effects of temperature on rocks and a volcanic eruption.

• The model includes what is needed for rocks to form but not their source.

• The model includes a path of formation but can be confusing to read.
