What is the most common element that living things and organic matter are made up of?
Answer: Carbon
100

What is the process used by scientists to determine the age of fossils?

Carbon dating

100

What is the epicentre of an earthquake?

Directly above the focus- the first place to feel the earthquake

100
Who came up with the continental drift theory?
Alfred Wegener

What type of boundary creates new seafloor?

divergent

200

Question: What are the two types of crust?

Oceanic and continental

200
Guess the question to this answer: 4.6 billion years old
Question: What is the age of Earth?
200
What is the law that states that the lower you go, the older the fossil?
The law of superposition
200

Which layer of the earth is broken up into pieces called tectonic plates? 

Lithosphere(upper mantle and crust)

200
What is the 'scar' on the ocean floor called?
The mid-ocean ridge
300

Which of the plate boundaries creates eartquakes?

All

300

What is an isotope?

Atoms of an element with the same atomic number but different masses. Therefore they are the same element but have  adifferent number of neutrons

300
What is 'half-life'?
The time it takes for a radioactive isotope to decay to 50% of the original amount.
300

What is the name of the supercontinent?

Pangaea 

300
How does new landmass form from the mid-ocean ridge?
Hot magma rises to the ocean floor, cools and solidifies to form new plate material/land mass.
400

What is the primary cause of earthquakes and volcanoes?

Crustal plate movement(or convergent, divergent and transform movement)

400

What is created when two continental plates converge?

Give an example of one 

Mountains/mountain ranges. 


Himalayas were formed this way


400
How would you find the half-life of a radioactive isotope if you were given a graph showing its radioactive decay against time?
Find 50% on the y-axis (radioactive decay), join it up to the graph and match it up with its corresponding x-axis value (time).
400

what are the three types of boundaries? 

Divergent, convergent, transform

400
How is magnetic striping evidence for plate movement?
The ocean floor holds records of the Earth's magnetic polarity over time. Hot magma rising from the mid-ocean ridge solidifies and forms new plate material. This plate material would reflect the Earth's magnetic polarity at the time. Evidence have showed that the position of this solidified material has moved over time, away from the opening of the mid-ocean ridge.

What is the place on the earth with the most volcanoes and earthquakes, and why do they experience so much here?

Ring of fire- surrounding a tectonic plate

500

What is Ms Rogash's favourite colour?

Pink

500

What is subduction and give an example

denser plates move under less dense plates. 

e.g. oceanic moves under continental

500
How does the existence of glaciers in certain continents give evidence for continental drift?
Glaciers are found in warm, tropical regions of Earth. These glaciers are remnants that were connected with Antarctica. These glaciers are also located at the southern regions of known continents.

Which of the tectonic boundaries can create volcanoes?

Convergent and transform
