What is the difference between the Earth's revolution and rotation?
Earth's rotation takes 24 hours, and its revolution takes one year (365 days).

What are adaptations and name three examples.
Adaptations help animals survive. Examples include camouflage, sharp teeth for tearing meat, and fast legs for catching prey.

Name four ways to classify rocks.
Color, hardness, streak, luster, cleavage, magnetism, etc.

What is the difference between food webs and food chains?
A food web is a collection of many food chains.
300
What is the difference between insulators and conductors?
Insulators do NOT allow heat or light to move through them easily. Conductors allow heat and light (electricity) to pass through.

Why do we have day and night on Earth?
Earth is rotating on its axis.

What are consumers, producers, and decomposers?
Producers make their own food (plants). Consumers eat producers and other consumers. Decomposers break down dead and decaying things on Earth.

How are sedimentary rocks formed?
Sedimentary rocks are formed by sediment that is pressed together via pressure.
300
What are natural resources?
Natural resources are things we use from nature like wood, rocks, etc.

What is the difference between pitch and volume?
Volume is how loud or soft a sound is and pitch is how high or low the sound is.

Why do we have seasons?
Earth is tilted on its axis and it revolves around the sun.

What is the difference between learned behaviors, like how to catch prey, and inherited traits, like hibernation and migration?
Inherited traits were passed down by parents and animals were born with them. They cannot be changed. Learned behaviors are learned after birth and can be changed.

How are metamorphic rocks formed?
Metamorphic rocks are formed when rocks are reheated or pressured and changed to make new rocks.

What are three states of matter and how can they change?
Solid, liquid, and gas. They can change by being heated and evaporated, condensation, etc.

What is the difference between carnivores, herbivores, and omnivores?
Carnivores eat meat only, herbivores only eat plants, and omnivores eat both plants and meat.

Explain the rock cycle.
Rocks can become igneous, sedimentary, or metamorphic based on heating, cooling, weathering, and erosion. Blah, blah, blah.
