Which of the following is NOT a function of the Earth's mantle?

Protecting Earth from space debris

If the tilt of Earth's axis increased, what would most likely happen to the seasons?

Seasons would become more extreme

They would become less noticeable

The length of a year would change

Which scenario best shows competition between organisms?

Two birds building nests in the same tree

How does the composition of the Earth's core differ from the mantle?

The core is mostly iron and nickel, the mantle is silicate rock

The core is made of rock, the mantle is metal

The core is liquid, the mantle is solid

The core is made of water, the mantle is made of air

Which of the following best explains why neap tides are weaker than spring tides?

The Sun and Moon pull at right angles, reducing their combined effect

The Earth blocks the Moon's gravity

Which statement best describes the function of the Earth's crust?

It provides a solid surface for life

It generates Earth's magnetic field

It is the source of Earth's gravity

Why is the cell theory important to biology?

It describes the basic unit of life

It tells us why the sky is blue

If two species compete for the same food source, what is a possible outcome?

One species may outcompete the other

Both species will increase in number

Both species will become extinct immediately

Which of the following best describes how abiotic factors can affect biotic factors?

Temperature can limit where plants grow

A scientist observes that when the Moon is full or new, the difference between high and low tides is greatest. Using evidence, explain why this happens.

The Sun and Moon's gravity combine, increasing tidal range

The Sun and Moon's gravity cancel each other out

The Earth's gravity is stronger at these times

A forest is experiencing a drought. Predict how this abiotic factor might affect the biotic factors in the ecosystem.

Plants may die, leading to less food for animals

Given the cell theory, what can you infer about the origin of new cells in your body?

They are created by existing cells dividing

They come from non-living material

A new species of plant is introduced into an ecosystem and quickly spreads. How might this affect competition among existing plant species?

Competition for resources will increase

The new plant will not affect anything

Explain how the movement of tectonic plates in the mantle can lead to earthquakes.

Plates move and sometimes get stuck, then release energy suddenly

The core heats up and melts the crust

A pond receives extra nutrients from nearby farms, causing algae to grow rapidly. How does this change affect the pond's ecosystem?

Algae use up oxygen, harming fish and other organisms

If the Earth's outer core stopped moving, what would be the most likely consequence for life on Earth?

The magnetic field would disappear, exposing Earth to harmful solar radiation

A population of rabbits and a population of deer both eat grass in a meadow. If the grass supply decreases, what is a likely outcome?

Both populations may decrease due to less food

The rabbit population will increase

The deer will stop eating grass

A student claims that all living things are made of cells, but viruses are not made of cells. Using cell theory, evaluate this claim.

The claim is correct; viruses are not considered living because they are not made of cells

The claim is incorrect; viruses are living things

The claim is correct; viruses are made of cells

The claim is incorrect; all things are made of cells

It is summer in the souther hemisphere at position 4.

It is fall in the northern hemisphere at position 3

It is winter in the northern hemisphere at position 2.

It is summer in the northern hemisphere at position 3
