what is a divergent plate boundary
tectonic plates pull away from eachother
how to plants affect the hills where they grow?
lots of plants allow for the least amount of erosion
the arrows in a food chain/web show what?
the way energy flows through an ecosystem
what is amplitude?
the height of a wave

S. Wave 3 has a shorter wavelength than Wave 2.
what's the difference between weathering and erosion?
weathering- earth breaks down
erosion- it moves to a new place
what is a transform plate boundary
when tectonic plates slide past each other
Earth has a magnetic field. Scientists think that this is partly because of magnetic materials found in some layers of Earth. The diagram shows the makeup of Earth’s layers.
Outer Core and Inner Core

Fertilizer makes plants grow bigger and faster. S. Fertilizer disrupts the healthy balance of the soil.
S. Fertilizer disrupts the healthy balance of the soil.

A student uses a laser pointer and a shiny surface to model a reflection on the surface of water. How does the model relate to the student seeing a reflection on the surface of the water? M. The light being refracted at point B is like the refraction of her image through the water and into her eye. P. The light being reflected at point B is like the light being reflected off the surface of the water and into her eye. R. The light being transmitted at point A is like the transmission of her image through the water and into her eye. S. The light being reflected at point A is like the light being reflected off the surface of the water and into her eye.
P. The light being reflected at point B is like the light being reflected off the surface of the water and into her eye.
a metal ball is thrown into a container of clay at different speeds each time the ball makes a dent in the clay.
trial 1- fast - 4 mm
trial 2- medium- 2mm
trial 3- slow- 1mm
write a statement using evidence above to explain how speed affect energy
a ball thrown at a fast speed makes the biggest dent because it has the largest amount of energy
