1. Erosion: moving sediments
2. Deposition: Sediments pile up
Three Top agents of Erosion:
1. Wind
2. Moving Water ( Most common on Earth)
3. Glaciers ( Most important in NYS history)
Stream or rivers erode in a V shape valley.
Stream velocity depends on:
1. The slope of the stream. ( Steeper is faster)
2. The stream discharge, (amount of water in a stream) more water, like after a heavy rain or Spring snow melt = faster water in a stream.
Stream Stages
1. Young Stage:
a. Steep slope, therefore faster moving water.
b. Most erosion is downward, making the valley deeper.
c. Straight flowing stream with rapids and water falls.
2. Mature Stage:
a. Flat or gentle slope, therefore water moves slowly.
b. Sideways erosion making wider valley.
c. Meanders occur and oxbow lakes form.
Global: Study all your notes about Mycenaean civilization, Minoans, Athens and Sparta.Athens and Sparta
Athens- was the most famous of all the city-states of ancient Greece. It was the birthplace of democracy and home to great philosophers like Plato and Socrates. It was also home to historians, scientists, mathematicians, and other great thinkers. Athens was famous for its giant fleet or ships, which they used to help defeat the Persians. A great rivalry with another city-state, Sparta led to the Peloponnesian War. This war eventually ended in a victory for Sparta.
Ancient Greece wasn't one large empire but a collection of smaller city-states. The term the Greeks used was polis, which means “city-state”. A polis was bigger than a city but smaller than a state. They were scattered throughout the Mediterranean area. Some were sea-ports while others were more inland. The two most famous city-states were Athens and Sparta. Although the people living in these city-states were all Greek, each city-state did different things and had different beliefs.

ATHENIAN SOLDIER COMBAT READYSparta- had the strongest military of all ancient Greek city-states. The focus of this city-state was constantly on war. Boys were expected to be trained as soldiers, while girls were expected to grow up and bear children who grew up to be soldiers. To make sure that the army got as many Spartan soldiers as it needed, Sparta depended on slaves from nearby settlement to do their manual labor. When the Greeks were at war with Persia, many people turned to the Spartans to ensure their protection.
