100
What is the term for the study of different parts of Earth?
Earth science
100
What is the outermost layer of Earth where we live?
The crust.
100
Name the plate boundary 1, 2, 7
North America Plate; Pacific Plate; Africa Plate
100
What happens at a divergent plate boundary?
Volcanic activity and shallow earthquakes.
100
What is the process called when heat travels through empty space?
Radiation.
200
What type of scientist studies volcanoes?
Volcanologist
200
What are the two types of crust found on Earth?
Continental crust and oceanic crust
200
What are the names of plates 8 and 9?
Eurasia Plate; Arabia Plate
200
What is the term for when one tectonic plate dives beneath another?
Subduction.
200
In which type of heat transfer do particles come into contact to transfer energy?
Conduction
300
What do meteorologists study in relation to Earth's atmosphere? (2 things)
Meteorologists study weather and climate.
300
What drives the movement of tectonic plates in the Earth's mantle?
Convection currents
300
Where is the Filipino Plate and India Plate?
12, 10
300
How deep are shallow earthquakes typically found?
Between 0 and 70 km deep.
300
What types of heat transfer involve when you are boiling water in a pot?
Radiation, conduction, convection
400
In what ways do meteorologists and oceanographers contribute to public safety?
Meteorologists provide weather forecasts to warn about severe weather, while oceanographers study ocean health and its effects on climate, which can also impact weather patterns.
400
Despite being above the melting point of iron, why is the inner core solid?
Because of the intense pressure of nearly 3.6 million atmospheres.
400
What is the name of the plate which locates below the cocos plate?
Nazca plate (3)
400
What type of plate boundary is characterized by plates sliding past each other, and what is the typical earthquake activity associated with it?
Transform boundary; it produces shallow earthquakes.
400
What is the name of the single circular motion created in the mantle due to convection currents?
Convection cell
500
Why is astronomy considered a branch of Earth science?
Astronomy is considered a branch of Earth science because astronomers use information about other planets and stars to learn more about Earth, particularly how solar changes may impact our planet.
500
What is the primary component of Earth's outer core and its role?
Liquid iron; it is responsible for Earth's magnetic field.
500
Which plate has the most volcanic activity?
2 (Pacific plate)
500
What geological feature forms above a hotspot where a tectonic plate rides over a rising plume of hot mantle?
A line of volcanoes forms above a hotspot.
500
Explain how convection currents in the mantle contribute to the movement of tectonic plates
Convection currents transfer heat from the Earth's interior, causing the mantle to flow and move tectonic plates above it.
