Why does the Moon have a greater effect on ocean tides than the Sun?

• The Moon has a greater gravitational pull on Earth's oceans because it is much closer

• The Sun is composed of gases which have no gravitational pull on Earth’s oceans

• The Moon is composed of a magnetic material which pulls on Earth’s oceans

• The Sun is much too far away from Earth to have any gravitational effects

Answer explanation

The Moon has a greater gravitational pull on Earth's oceans because it is much closer. While the Sun is massive, its distance from Earth reduces its tidal effect compared to the Moon.

The diagram provided depicts tidal height related to four moon phases. Which points in the diagram could represent the height of tides during the full Moon and the new Moon?

Select TWO answers.

• Point W

• Point X

• Point Y

• Point Z

Answer explanation

During the full Moon and new Moon, tidal heights are at their highest due to the alignment of the Earth, Moon, and Sun. In the diagram, Point W and Point Y represent these high tidal heights.

The interlocking crystals of igneous rock help to classify it since these crystals are evidence of how the rock formed. The crystals are a result of –

• sediments being deposited.

• particles forming layers.

• chemical reactions of minerals.

• melted rock that cooled.

Answer explanation

The interlocking crystals in igneous rock form when melted rock cools and solidifies. This process is key to classifying igneous rocks, as the crystal structure reflects the cooling history of the magma.

What letter in the diagram identifies the layer that is best described as a molten rock (magma) state?

• Layer A

• Layer B

• Layer C

• Layer D

Answer explanation

Layer B is identified as the molten rock (magma) state, as it represents the layer where rock is in a semi-liquid form, allowing for movement and flow, distinguishing it from the solid layers above and below.

What letter in the diagram identifies the layer that is composed of moving continental and oceanic plates?

• Layer A

• Layer B

• Layer C

• Layer D

Answer explanation

Layer A identifies the layer composed of moving continental and oceanic plates, known as the lithosphere. This layer is crucial for understanding plate tectonics and geological activity.

Which letter in the diagram identifies the layer of Earth that is best described as liquid metal?

• Layer A

• Layer B

• Layer C

• Layer D

Answer explanation

Layer C identifies the outer core of the Earth, which is composed of liquid metal, primarily iron and nickel. This distinguishes it from the solid layers above and below it.

Which letter in the diagram identifies the layer of Earth made up of solid nickel and iron?

• Layer A

• Layer B

• Layer C

• Layer D

Answer explanation

Layer D identifies the inner core of the Earth, which is composed of solid nickel and iron. This layer is crucial for understanding the Earth's composition and structure.

Jordan is asked to draw an image of where he might find igneous rock. Jordan can figure out where this rock would be found by learning how it is formed. Which of the following will most likely cause the formation of igneous rock?

• Mountain formation

• Faulting and folding

• Volcanic activity

• Earthquake activity

Answer explanation

Igneous rock forms from the cooling and solidification of magma or lava. Volcanic activity is the primary process that brings magma to the surface, leading to the formation of igneous rock, making it the correct choice.

During which moon locations does the smallest difference in the tidal range occur? Select TWO Answers.

• Location W

• Location X

• Location Y

• Location Z

Answer explanation

The smallest difference in tidal range occurs at locations where the gravitational pull of the moon is less variable. Locations W and Y experience this minimal variation, making them the correct answers.

Which moon locations represents neap tides? Select TWO Answers

• Location W

• Location X

• Location Y

• Location Z

Answer explanation

Neap tides occur when the moon is in the first and third quarters, leading to lower tidal ranges. Locations W and Y correspond to these positions, making them the correct choices for representing neap tides.
