Grade 6 Earth Science

What is the main cause of earthquakes?

• Volcanic eruptions

• Movement of tectonic plates

• Alien invasion

• Global warming

How are volcanoes formed?

• Volcanoes are a result of excessive rainfall in a region.

• Volcanoes are created by underground nuclear explosions.

• Magma from within the Earth's upper mantle works its way to the surface.

• Volcanoes are formed by meteorite impacts on the Earth's surface.

What is the Ring of Fire?

• The Ring of Fire is a region around the Pacific Ocean known for its seismic and volcanic activity.

• The Ring of Fire is a type of spicy food dish

• The Ring of Fire is a jewelry store chain

• The Ring of Fire is a popular dance move

Explain the difference between weather and climate.

• Weather is short-term, climate is long-term.

• Weather changes with altitude, climate does not.

• Weather only affects humans, climate affects the entire planet.

• Weather is predictable, climate is unpredictable.

What is the theory of plate tectonics?

• The theory of plate tectonics is related to the study of marine life.

• The theory of plate tectonics involves the study of outer space.

• The theory of plate tectonics explains the movement of the Earth's lithosphere.

• The theory of plate tectonics explains the formation of clouds.

How do scientists predict volcanic eruptions?

• By tasting the soil composition

• By observing cloud formations

• By counting the number of trees in the area

• By monitoring signs like seismic activity, gas emissions, ground deformation, and historical eruption patterns.

What are the different types of volcanoes?

• shield volcanoes, stratovolcanoes, cinder cone volcanoes, lava domes

• volcanic mountains, super volcanoes, geysers

What is the Richter scale used for?

• Measuring the magnitude of earthquakes.

• Calculating the distance between planets

• Measuring wind speed

• Determining the pH of a substance

How do earthquakes cause tsunamis?

• Earthquakes cause tsunamis by creating strong winds that push water towards the shore.

• Earthquakes cause tsunamis by triggering volcanic eruptions under the ocean.

• Earthquakes cause tsunamis by displacing large volumes of water in the ocean due to the sudden release of energy in the Earth's crust.

• Earthquakes cause tsunamis by altering the Earth's rotation and creating tidal waves.

What is the greenhouse effect and how does it impact the Earth's climate?

• The greenhouse effect is a man-made phenomenon that has no impact on the Earth's climate.

• The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun, leading to warming of the planet. This warming effect is essential for supporting life on Earth. However, human activities have intensified the greenhouse effect by increasing the concentration of these gases, leading to global warming and climate change.

• The greenhouse effect is caused by the depletion of the ozone layer, leading to cooling of the planet.

• The greenhouse effect is a process where the Earth's atmosphere reflects heat back into space, resulting in cooling.
