oxygen, 46.6 percent by weight; silicon, 27.7 percent; aluminum, 8.1 percent; iron, 5 percent; calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent.
What does BOLTSS stand for?
Border, orientation, legend, title, source, scale
Explain how tsunamis occur
earthquake under the sea, rising height of wave, sweeping destruction - teacher to confirm
What are the effects of a converging plate boundary?
mountains, earthquakes, volcanoes
This term describes the theory that the Earth’s crust is divided into twelve major sections which are moving in various directions.
Tectonic Plate Theory
What is the crust divided into?
Tectonic plates
What is a contour interval?
The distance (or height) between each contour line.
What is one social, economic and environmental ADVANTAGES of living near a volcano?
teacher to confirm
What are the effects of a transform boundary?
earthquakes, tsunamis, landslides
This term refers to the process of two tectonic plates that are moving away from each other, creating a rift or trench
Diverging plate boundary
What is the mantle made of?
Magma and silicate rocks rich in magnesium and iron.
What is a spot height?
the highest point on a mountain in a contour map
What is one social, economic and environmental DISADVANTAGE of living near a volcano?
teacher to confirm
What are the effects of a diverging plate boundary?
trench, volcano, new land
This term refers to the process of two tectonic plates that are moving towards each other, creating mountains
Converging Plates
Bonus: what is it made of?
liquid: nickel-iron alloy
How can you tell a steep area from a gradual slope on a contour map?
Steep areas have contour line very close together and gradual slopes are further apart.
How did Hawaii form? Explain the process.
Hotspot, convection - teacher will confirm correct answers.
Where is the Pacific Ring of Fire? What are the effects of the boundary around this plate?
around the pacific tectonic plate, many earthquakes and volcanoes.
This term refers to the lithosphere that floats on top of the mantle
Crust
What are 2 facts about the inner core?
it is a solid core made of iron. It spins at a different speed to the rest of the earth. It is thought to cause the earth's magnetic field.
Explain how contour lines on a map help to identify land features.
contour lines show the height above sea level, each line represents a different height and this is how we can see features such as mountains and valleys in 2D.
How did Uluru form? Explain the process.
Fans, compression, tectonic plates, erosion - teacher will confirm correct answers
What causes tectonic plates to move? Explain the process
convection - teacher to confirm
