Earthquakes may be caused by
-
Plates sliding past each other
-
Lava flowing down the side of a volcano
-
Plates spreading apart
-
Hot magma
Correct Answer
A. Plates sliding past each otherExplanation
Earthquakes can occur when tectonic plates, which make up the Earth's crust, slide past each other. These plates are constantly moving, and when they get stuck, pressure builds up until it is released in the form of an earthquake. This movement can happen along faults, which are fractures in the Earth's crust. As the plates slide past each other, they can cause vibrations and shaking, resulting in an earthquake.Rate this question:

Mountains are formed by two divergent plates moving away from each other.
-
True
-
False
Correct Answer
A. FalseExplanation
Mountains are not formed by two divergent plates moving away from each other. Instead, they are formed by two convergent plates colliding with each other. When two plates collide, the force causes the crust to fold and buckle, resulting in the formation of mountains. This process is known as plate tectonics and is responsible for the creation of most of the world's mountain ranges.Rate this question:

What is magma?
-
Hot lava that erupts out of volcanoes
-
The reason volcanoes form
-
Mixture of molten rock found beneath the surface of the earth
-
All of the above
Correct Answer
A. Mixture of molten rock found beneath the surface of the earthExplanation
Magma is a mixture of molten rock found beneath the surface of the earth. This molten rock is in a highly heated and semi-liquid state, and it is the material that eventually erupts out of volcanoes as lava. Magma is the result of intense heat and pressure within the Earth's mantle, causing rocks to melt and form this molten mixture. It is the source of volcanic activity and plays a crucial role in the formation and eruption of volcanoes.Rate this question:

A mountain is formed after
-
An earthquake
-
A volcano erupts
-
Weathering
-
A storm
Correct Answer
A. A volcano eruptsExplanation
A mountain is formed after a volcano erupts. During a volcanic eruption, molten rock, ash, and other materials are ejected from the volcano and accumulate over time, forming a cone-shaped mountain. The volcanic activity contributes to the growth and formation of the mountain as the erupted materials solidify and build up. This process can occur over thousands or millions of years, gradually creating a mountainous landscape.Rate this question:

When the denser oceanic plate subducts under the continental crust, it ________ up and turns into magma.
Correct Answer
heatsExplanation
When the denser oceanic plate subducts under the continental crust, it undergoes intense heat and pressure. This causes the plate to heat up and melt, transforming into magma. The heat generated during subduction is a result of the friction and collision between the two tectonic plates. As the oceanic plate sinks deeper into the Earth's mantle, it experiences higher temperatures, causing the rocks to melt and form magma.Rate this question:

Plate tectonics is: a theory explaining that the Earth's outer layer (crust) is made up of large _______ ________ that are constantly moving over a weak layer of molten rock.
Correct Answer
moving platesExplanation
Plate tectonics is a theory that explains how the Earth's outer layer, known as the crust, is composed of large moving plates. These plates are constantly shifting and moving over a weak layer of molten rock beneath them. This movement of the plates is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.Rate this question:
