Question 3

Newton’s first law of motion

Answer 3

Law of inertia.

An object at rest stays at rest, and an object in motion stays in motion until a greater force is acted upon it.

Question 4

Newton’s second law of motion

Answer 4

Force = mass x acceleration

Question 5

Newton’s third law of motion

Answer 5

When 2 objects interact, they apply forces of equal magnitude and opposite direction.

Question 6

Types of rock

Answer 6

Igneous, sedimentary, metamorphic

Question 7

Igneous rocks

Answer 7

Form when molten rock (magma, lava) cools and solidifies.

Question 8

Sedimentary rocks

Answer 8

Particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.

Question 9

Metamorphic rocks

Answer 9

Existing rocks are changed by heat, pressure, or reactive fluids.

Question 10

Primary consumer
Producer aka autotroph
