Plate tectonic theory
State the four layers that make up the Earth
Crust
Mantle
outer core
inner core
List the 7 different type of Electromagnetic radiation present that exist
Radio waves, microwaves, infrared, visible light, ultra violet, X-rays and gamma rays
What are the two types of energy?
Kinetic energy potential energy
What is temperature?
temperature is the movement of particles in an object.
DNA is the genetic material found in the cells on a living creature
What are the two layers the crust is divided into
Continental crust and oceanic crust
Name another wave that exists besides light waves
Sound waves/longitudinal waves
any of the following:
light, sound, mechanical, wind, heat, geothermal etc. energy
Describe what happens to an object when it gains and loses thermal energy.
When it gains thermal enegry its particles move faster causing it to be warm
When it loses thermal enegry its particles move slower causing it to be cold
Store in the chromosome of the nucleus
What are the three types of plate boundaries
Transform
divergent
convergent
Which wave interaction causes the wave to change its direction at an angle when it passes through another medium
refraction
State the law of conservation of energy
Energy can neither be created nor destroyed only converted from one form to the next.
Explain how a insulator can keep an object warm
State two advantages of asexual reproduction
requires no mate
faster
produces more offspring
advantageous traits are passed on
Why is the core of the Earth solid despite the temperature being over 7000 degrees C
The pressure at the core of the Earth is so great it keeps the particles of the core compact and in a solid state
What is the phenomenon that occurs when light hits a black object and is not reflected back?
absorption
What energy change occurs when a flash light is turned on?
chemical energy --> electrical energy --> Light energy and heat energy
Gaining or losing thermal enegry can cause changes in teh states of an object
Which animal can reproduce using the fragmentation method
worms/starfish
What action causes the movement of plates on the earth's surface?
Convection currents within the mantle of the Earth
What is the relationship between wavelength and frequency in the EM Spectrum?
The larger the wave lenght the lower of frequency
The lower the eave length the higher the frequency
They are indirectly proportional
On a roller coaster, when does the car have potential kinetic energy and when is energy transferred?
Potential at the top of the ride
Kinetic as it travels down the slope
Energy transfer occurs when it starts to go down the slope
How does heat flow through an object?
Heat travels from an environment with a higher temperature to an environment with a lower temperature
How does the amount of genetic material in the parent cell compare to the daughter cell in mitosis?
they are identical
