About Earth

What evidence is there that the plates have moved?

Well the first piece of evidence is because there are fault lines. A fault line is a line on a rock surface or the ground that traces a geological fault. Also by earthquakes and convection currents . The plates are Continental plates and Oceanic plates. The types of boundaries are strike-slip, normal fault, and reverse fault. The way's that plates move are by radiation, conduction, and convection.

About Erosion

Facts about erosion

The erosion that can cause the most damage to earths surface is mass-movement erosion. The erosion that can cause the least damage to earths surface is surface damage.

Minerals

One way that minerals are formed is by the cooling of magma. Another way minerals are formed is by re-crystallization and living cells. We identify minerals is by color, luster, streak, hardness, cleavage, and specific gravity.

What I liked

What i liked about this unit is when i got to explore the rocks is Mrs. Johnson's rock box. I also liked it when we got to use the i pads and see what our birth stone was.
