Year 4 Mountains and Oceans Quiz

What are the three main types of mountains?

• Snowy mountains, rocky mountains, and sandy mountains

• Flat mountains, round mountains, and square mountains

• Fold mountains, block mountains, and volcanic mountains

• Desert mountains, ocean mountains, and forest mountains

How are fold mountains formed?

• Erosion and sediment deposition

• Tectonic plates collision and crustal uplift

• Volcanic eruption and lava flow

• Meteorite impact and crater formation

What are volcanic mountains and how are they formed?

• Volcanic mountains are formed by the movement of tectonic plates

• Volcanic mountains are formed by the erosion of sedimentary rocks

• Volcanic mountains are formed by the freezing of underground water

• Volcanic mountains are formed by the accumulation of lava, ash, and other volcanic materials from eruptions.

Explain the process of block mountains formation.

• Large areas of the Earth's crust are uplifted and tilted, creating steep, rugged mountain ranges.

• Block mountains are formed by the movement of tectonic plates.

• The mountains are formed by volcanic activity and the accumulation of lava.

• The mountains are formed by the erosion of the Earth's crust over millions of years.

How are oceans formed?

• Seafloor spreading

• Volcanic eruption

• Meteor impact

• Global warming

What are the major factors contributing to the formation of oceans?

• Meteor showers, earthquakes, and hurricanes

• Global warming, pollution, and deforestation

• Glacial melting, soil erosion, and desertification

• Tectonic plate movement, volcanic activity, and erosion

Describe the role of plate tectonics in the formation of oceans.

• Plate tectonics have no impact on the formation of oceans

• Plate tectonics create ocean basins and move continents

• The formation of oceans is solely due to erosion and weathering

• Oceans are formed by volcanic eruptions

What is the importance of marine life in oceans?

• Maintaining ecosystem balance, providing food and resources, and contributing to oxygen production

• Contributing to pollution in the oceans

• Decreasing oxygen production

• Causing imbalance in the ecosystem

Name three examples of marine life found in oceans.

• Sharks, whales, and penguins

• Octopus, seals, and seagulls

• Fish, dolphins, and sea turtles

• Seahorses, crabs, and jellyfish

Explain the concept of ocean food chains and its significance in marine life.

• Ocean food chains have no impact on the balance of marine ecosystems

• Ocean food chains are unrelated to marine life

• Ocean food chains are interconnected feeding relationships in marine ecosystems, significant for maintaining balance and supporting the survival of various species.

• Ocean food chains only involve one species of marine animals
