What does the LAW OF SUPERPOSITION state?
What is the law of superposition states that older rocks are on the bottom of Earth's layers and younger rocks are on the top.
The ___________heats the Earth unevenly. It is hotter at the equator than at the poles. This uneven heating causes ___________ currents in the air.
The SUN heats the Earth unevenly. It is hotter at the equator than at the poles. This uneven heating causes CONVECTION currents in the air.
What is the term for when sediments are dropped onto another location. Often landforms such as river deltas are formed through this process.
What is DEPOSITION?
How does SEDIMENTARY rock form?
What is through the compaction of sediments?
Give an example of a landform created by tectonic plate movement.

The movement of wind, water, and waves contribute to our ever changing landforms. They __________ and ___________our beaches and mountains.
What is...The movement of wind, water, and waves contribute to our ever changing landforms. They WEATHER and ERODE our beaches and mountains.
______________ _______________ is heat in the Earth that causes molten rock in the mantle to move. This hot rock rises, cools, then sinks again, creating CONVECTION CURRENTS.
What is THERMAL CONVECTION.
Why is SEDIMENTARY rock so important for us, in Lansing, N.Y. (Hint: what do you find in it and how does this help us learn about Earth?)
SEDIMENTARY rock is important for us in Lansing, N.Y. because we find Trilobites (or Index fossils) which help us learn about the age of our area.
