Which BEST describes the role of mid-ocean ridges in the theory of plate tectonics' connection to continental drift?

Mid-ocean ridges are underwater mountain ranges where plates diverge.

Where one plate is sinking beneath another.

How do interactions between Earth's layers contribute to earthquakes and volcanic activity?

Convection in the mantle drives the movement of tectonic plates.

Which of the following BEST demonstrates the relationship between earthquakes and volcanic eruptions?

Both are caused by the movement of tectonic plates.

What happens at a convergent boundary between an oceanic plate and a continental plate?

The oceanic plate subducts beneath the continental plate.

What should a scientist do if the results of an experiment fail to support the hypothesis?

Revise the hypothesis and conduct further experiments.

Why should scientists share finding of their experiments with other scientists?

To allow others to verify and build upon their work.

Which of the following MOST LIKELY explains the formation of a volcanic island chain?

Tectonic plates move slowly over a hot spot and form chains of volcanoes.

How does the theory of plate tectonics explain the formation of mountain ranges and earthquakes?

Mountains form as plates collide/earthquakes occur as plates slide/collide

Which of the following best describes why plate tectonics is a theory?

It explains the events and could be updated with new evidence.

What function does slab pull have in the process of plate tectonics?

It pulls tectonic plates into the mantle at subduction zones.

Why is it significant that fossils were found on separated continents?

It suggests that the continents were once connected.

What is the relationship between mantle convection and tectonic plates?

Mantle convection drives the movement of tectonic plates.

Which of the following BEST describes the relationship between subduction and volcanic activity?

Subduction zones often lead to the formation of volcanic arcs.

Answers

1
Which BEST describes the role of mid-ocean ridges in the theory of plate tectonics' connection to continental drift?
Mid-ocean ridges are underwater mountain ranges where plates diverge.
Mid-ocean ridges are underwater mountain ranges where plates converge.
Mid-ocean ridges are underwater mountain ranges where plates collide.
Mid-ocean ridges are underwater mountain ranges at transform boundaries.
2
A subduction zone is
Where two plates are moving apart.
Where one plate is sliding past another.
Where two plates are colliding and forming mountains.
Where one plate is sinking beneath another.
3
How do interactions between Earth's layers contribute to earthquakes and volcanic activity?
The inner core makes the crust to expand and contract, causing volcanoes.
Oceanic crust sinks into the mantle leading to volcanic activity.
Convection in the mantle drives the movement of tectonic plates.
The outer core makes the crust to expand and contract causing volcanoes
4
Which of the following BEST demonstrates the relationship between earthquakes and volcanic eruptions?
Volcanic eruptions cause earthquakes.
Both are caused by the movement of tectonic plates.
Earthquakes cause volcanic eruptions.
They are NOT related.
5
What happens at a convergent boundary between an oceanic plate and a continental plate?
The continental plate subducts beneath the oceanic plate.
The plates move farther away from each other.
The oceanic plate subducts beneath the continental plate.
The plates move past each other horizontally.
6
What is the result of seafloor spreading?
Creation of deep ocean trenches
Subduction of old oceanic crust
Formation of mountain ranges
Creation of new oceanic crust
7
What should a scientist do if the results of an experiment fail to support the hypothesis?
Ignore the results.
Change the data to support the hypothesis.
Revise the hypothesis and conduct further experiments.
Publish the incorrect results.
8
What geological feature is usually found at convergent boundaries between two continental plates?
Mid-Ocean Ridge
Mountain Range
Rift Valley
Ocean Trench
9
What process is responsible for formation of ocean basins?
Erosion
Subduction
Seafloor Spreading
Convergence
10
Why should scientists share finding of their experiments with other scientists?
To protect the secrecy of their work.
To allow others to verify and build upon their work.
To prevent others from finding the same information first.
To gain fame and make large amounts of money.
11
Which of the following MOST LIKELY explains the formation of a volcanic island chain?
Transform boundaries slide against each other and magma rises to the top.
Tectonic plates move slowly over a hot spot and form chains of volcanoes.
Convergent boundaries force rocks off their edges up to become islands.
Sediments piled up.
12
How does the theory of plate tectonics explain the formation of mountain ranges and earthquakes?
Mountains form from sediment/earthquakes occur at divergent boundaries.
Mountains form as plates collide/earthquakes occur as plates slide/collide
Mountains form at divergent plates/ earthquakes at transform plates
Mountains and earthquakes are unrelated to plate tectonics.
13
Which of the following best describes why plate tectonics is a theory?

It has not been proven through experiments.
It explains the events and could be updated with new evidence.
14
At which type of boundary is a rift valley most likely to form?
Divergent
Slab Pull
Convergent
Transform
15
What function does slab pull have in the process of plate tectonics?
It causes tectonic plates to slide past each other at transform boundaries.
It pulls tectonic plates into the mantle at subduction zones.
It lifts tectonic plates to form mountain ranges.
It pushes tectonic plates apart at divergent boundaries.
16
At which type of boundary are earthquakes most likely to occur?

transform
Convergent
Slab pull
17
Which type of plate boundary forms when two plates move away from each other?
Convergent
Subduction
Divergent
Transform
18
Why is it significant that fossils were found on separated continents?
It indicates that similar species evolved on different continents.
It suggests that the continents were once connected.
It proves that climate was similar across all continents in the past.
It shows that ocean currents carried fossils across vast distances.
19

20
What is the relationship between mantle convection and tectonic plates?
