First 3 Chapters
This type of substance can always be found on the Periodic Table.
→ What is an element?
Heat transfer that occurs by touching a hot object.
Conduction
This movement is a planet spinning on its axis.
→ What is rotation?
This force keeps planets in orbit around the Sun.
Gravity
Earth is in the “Goldilocks Zone,” meaning this.
→ What is it’s not too hot, not too cold?
This type of substance forms when two atoms bond chemically to make something new.
→ What is a compound?
This type of heat transfer happens in boiling water.
Convection
This rocky region lies between Mars and Jupiter.
The Asteroid Belt
The two forces that create an orbit are gravity and _______
Inertia
Earth supports life partly because this substance can be found in liquid form.
Water
In the formula CaCl₂, this element has two atoms.
→ What is chlorine?
This type of energy transfer is why you can feel the Sun’s heat without touching it.
Radiation
This icy region beyond Neptune contains dwarf planets like Pluto
→ What is the Kuiper Belt?
Earth has more gravity than Mars because it has more of this.
→ What is mass
Earth’s atmosphere contains this gas needed for most living things.
Oxygen
Dissolving sugar in water is this type of change.
Physical Change
A jacket works because it is a good _______.
Insulator
These objects come from the Oort Cloud and develop tails near the Sun
→ What are comets?
Moons orbit planets because of this.
→ What is the planet’s gravity?
Name two reasons Mars cannot support life like Earth
→ What are: thin atmosphere, too cold, little liquid water, no oxygen,
A gas forming without boiling is evidence of this type of change.
→ What is a chemical change?
Metal feels cold because it transfers heat away from your hand quickly. This makes it a good ______.
Conductor
Name three differences between inner & outer planets
1. Distance from the Sun
2. Size
3. Moons & Rings
If Earth suddenly stopped moving forward, this would happen
→ What is it would fall into the Sun?
What protects Earth from harmful UV Radiation from the Sn?
The atmosphere
