How tightly particles are packed together. Independent of the size of the sample.
Heat energy is unable to flow easily through it. (Examples - Glass, wood, plastic, rubber)
Caused by the gravitational pull between the Earth and moon.
Earth's is breathable due to the unique mixture of gases.
Keeps water and gases in the atmosphere close to Earth's surface which contributes to life processes.
3/4 water and 1/4 land
Solid inner surrounded by a liquid outer
Convection currents in the mantle
Cause plates to move several centimeters each year.
Sound waves and P waves - The disturbance transports energy, not matter. Parallel pulses. Compressions and rarefactions.
Light waves - Perpendicular. Crests and troughs.
Mainly composed of weathered parent rock, but also includes air and water. Produces faster in warm, wet regions.
A plant bends toward the light source.
An inactive time when plants are waiting for the right temperature, amount of water and sunlight to grow or bloom.
Travels slowest in air because of the increased distance between air particles. Travels fastest through a metal rod.
Smallest part of an element. Has mass and volume. Building block of all things. Composed of matter.
A change affecting the form, but not the chemical composition of an object. (Crushing a can)
Irreversable making or breaking of chemical bonds between atoms forming a new substance. (Rusting of a can)
Formed by melting rock, volcanoes.
Formed by sediment being compacted together
Formed by heat and pressure inside the earth
Created by changing angles (relative positions) of the earth, the moon and the sun, as the moon orbits the earth.
Solid outer part of earth consisting of the upper mantle and crust.
When one plate slides under another.
A process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity. (Formed Hawaiin islands)
Bending of a wave when it enters a medium where its speed is different
Heat energy is able to flow easily through it. (Silver, copper)
Caused by the tilt of earth on its axis as it moves around the sun.
Center of our solar system
Pollen from the stamen gets into the ovary
How often a wave vibrates. (Faster makes a higher pitch. Slower makes a lower pitch.)
The strength of a wave measured from the crest to the trough of a wave.
Distance between crests of adjacent waves.
Plants use sunlight and carbon dioxide to make their own food.
Moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
Energy which flows in a circuit.
Moving of soil or rock from one location to another. Can be prevented through soil conservation.
Breaking down of rocks, soil and minerals.
Heat transfer between materials that are touching.
Heat transfer by movement of particles rising and falling.
Heat transfer through empty space.
Molecules are closely packed and do not flow freely. (Ice)
Molecules can slide past each other and move a little more freely. (Soda)
Molecules a free flowing. (Bubbles)
Light reflects off an object and then enters the eye, allowing people to see the object.
Part of the electromagnetic spectrum that can be seen with the eye.
Makes atoms vibrate faster or slower.
Remains the same for identical elements, but the process may occur more quickly or slowly based on the amount.
Reveals weather and climate patterns that occur on Earth.
Composed of Continental and oceanic plates.
Dependent on soil texture and the amount of water it can hold.
Produces and stores pollen.
Sun to producers to consumers to decomposers
