Forces of Nature
States of Matter
Rock Cycle
Water Cycle
Carbon Cycle
100

This force pulls objects with mass toward each other.

Gravity

100

Particles are packed tightly, with a fixed shape and fixed volume. 

Solid

100

This rock forms when magma or lava cools. 

Igneous Rock

100

Heat from the Sun turns liquid water into vapor in this SET process. 

Evaporation 

100

The mnemonic LEEGC, which sounds like "Legacy," helps you remember this cycle. 

Carbon Cycle 

200

This force acts between electric charges and magnets.

Electromagnetism

200

This state takes the shape of its container but keeps a fixed volume. 

Liquid

200

This rock forms from layers of compacted and cemented sediment. 

Sedimentary Rocks

200

Plants release water vapor through their leaves in this SET process

Transpiration

200

The L in LEEGC stands for this, including plants and animals that take in and release carbon. 

Life

300

This strongest force holds protons and neutrons together in the nucleus. 

Strong Nuclear Force

300

This state spreads out to fill any container.

Gas

300

This rock is changed by heat and pressure. 

Metamorphic Rock

300

Water moving deeper down through soil and rock layers is this PICDP process.

Percolation

300

The two E's in LEEGC stand for these. 

Energy and Ecosystem

400

*Daily Double : This force is behind radioactive decay

What is Weak Nuclear Force

400

This superheated, charged state makes up the Sun and the stars. 

Plasma

400

This process breaks rock into smaller pieces. 

Weathering

400

DAILY DOUBLE: SET stands for these three processes that send water up.

Sublimation. Evaporation and Transpiration

400

Plants taking in carbon dioxide to build tissue connects to this G in LEEGC

Growth

500

Scientists recognize this many fundamental forces of nature.

Four

500

TRIPLE DOUBLE: This fifth state forms when atoms are cooled near absolute zero and act as one. 

Bose-Einstein Condensate

500

Wind, water, and ice carry sediment away in this process. 

Erosion

500

PICDP stands for these five processes that send water down. 

What are precipitation, infiltration, condensation, deposition, and percolation?

500

Carbon dioxide trapping heat links the cycle to this C in LEEGC, also called temperature. →
