Earthquakes can happen along several types of plate boundaries.

Explain how an earthquake takes place along a transform plate boundary.

• The grinding action between the plates of a transform plate boundary, result in shallow earthquakes.

• large magnitude between plate boundaries

• Because of the natural force of the earth

Answer explanation

The grinding action between the plates of a transform plate boundary, result in shallow earthquakes.

Earth is divded into three compositional layers. Tell and describe where it would be on earth

• Crust: outer layer, where humans live

• Mantle: magma layer consisting of iron, and silicon

• Core: solid mass of metal (inner core), and liquid mass of iron and nickel (outer core)

• Lithosphere: the rigid outer part of the earth, consisting of the crust and upper mantle

Answer explanation

The correct choices describe the compositional layers of Earth: Crust (outer layer), Mantle (magma layer), and Core (solid inner core, liquid outer core).

True of false tectonic plates are not earths most outer layer

• True

• False

Answer explanation

False because tectonic plates are part of the Earth's lithosphere, which is the outermost layer of the Earth.

How does a mineral color and luster differ?

• It is extremely malleable, and is usually found in a pure form

• High intensity creating a sparkling or glittering effect

• They both resemble fat or grease

Answer explanation

Mineral color is due to impurities or chemical composition, while luster is the way light reflects off the mineral's surface. The correct choice highlights the malleability and purity of minerals.

What is the primary cause of volcanic eruptions?

• Movement of tectonic plates

• Changes in atmospheric pressure

• Solar flares

Answer explanation

The primary cause of volcanic eruptions is the movement of tectonic plates.

True or false: The Earth's core is composed mainly of iron and nickel.

• True

• False

Answer explanation

True because the Earth's core is primarily made up of iron and nickel, which are dense metals that make up the majority of its composition.

Which type of rock is formed from the cooling and solidification of magma or lava?

• Sedimentary rock

• Igneous rock

• Metamorphic rock

Answer explanation

Igneous rock is formed from the cooling and solidification of magma or lava, making it the correct choice.

How is a strike slip fault different from a normal reverse fault?

• As a strike slip occurs boundaries form

• That reverse are compressional forces

• Reverse faults are common in areas of compression

• A strike slip is a boundary from two tectonic plates

What is the difference between uplift and subsidence?

Answer explanation

The answer: subsidence is a lowering or collapse of the ground

Uplift is the converse
