Rock transformations
What are the three different types of rocks
igneous, metamorphic, sedimentary
If you put a spoon in a hot pot and the spoon gets hot, what heat transfer is this.
conduction
How do earthquakes form
Tectonic plates shifting causing the ground to vibrate
There are dark grass hopper and light grasshopper, their environment is more dark and shaded. Predators are able to pick out the light colored ones easier. what will happen to the population.
Overtime the population becomes darker due to predators being able to locate the lighter colored grasshoppers easier.
A whale has a pelvic bone but is aquatic, is this vestigial structure and why.
This is vestigial because it is not of use to the whale.
How do sedimentary rocks form.
sediment compacts cements.
what are the three types of thermal energy transfers.
conduction, convection, radiation
what plate boundaries do mountains form in
Giraffes with longer neck can reach food easier with those with short necks; what will happen to the population overtime.
The long neck trait will become more common.
if two animals have homologous bone structure, what does that mean
The structure of the bones are the are the same but used for different purposes.
Can metamorphic rock become another type of rock
yeah it can become sedimentary
how are convection currents created
Different densities in liquid rising and falling forming currents.
what geological events occur from earthquakes.
tsunamis, volcanoes eruptions, an tsunamis.
what is natural selection.
overtime traits that are useful to a population becomes more common.
What are heterozygous bone structures.
Bone structures that are shaped different but serve the same function.
can igneous rock form underground and above ground
yes
What is the difference between thermal energy and temperature
temperature measures the average kinetic energy of particles, while thermal energy is the total energy of all particles in a substance.
What is the lithosphere?
It is the rigid outer layer of Earth, roughly 100 km thick, consisting of the crust and the uppermost part of the mantle.
What happens when plates diverge on land
A rift valley forms
it is change in a species
What happens to solid rock when it moves deep into Earth's interior and is exposed to extreme heat
it is heated and shaped
In which direction does thermal energy always flow
It naturally moves from an area of higher temperature to an area of lower temperature.
What are Divergent Boundaries
Where plates pull apart.
What is subduction
It is the process where a denser oceanic plate sinks beneath a less dense continental plate into the mantle.
how does DNA show evidence of common ancestry
It shows their structures and what previous and current species they are similar to
