Why is Cambrian explosion a significant event in geologic history?

Many organisms have rapidly evolved during this period

Many organisms have gone extinct during this period

Many organisms have remained the same throughout this period

Many organisms have migrated to another place during this period

Which correctly describes accumulation during water cycle?

The water flows on the land and eventually collects in different bodies of water.

The water vapor collects and form clouds filled with water droplets.

The clouds become heavier and eventually pours down as rain or snow.

The sun heats up the ocean causing the liquid water to change into gas.

Which statement is true about a weather hazard?

A weather hazard has a potential to cause harm or damage.

A weather hazard cannot be predicted.

A weather hazard always results in a long-term effect.

A weather hazard may bring economic growth to a country.

Which of the following is not an example of point source pollution?

water runoff from residential lawns

oil that is escaping from a damaged tanker

heavy metals that are leaching out of an underground mine

untreated sewage that is accidentally released from a wastewater treatment plant

Once the experiment is done, mix leftover chemicals to easily dispose them. Is this statement correct?

No, this statement is incorrect. Leftover chemicals should not be mixed for disposal unless instructed by proper safety guidelines.

Yes, mixing leftover chemicals is always the safest way to dispose them.

It is acceptable to mix chemicals if they are in small quantities.

Mixing chemicals after experiments is recommended for faster cleanup.

Refer to the diagram of the Hertzsprung-Russell diagram showing star categories, luminosity, and temperature. What characteristic of sun is plotted on the:

a. x-axis: Temperature (Kelvin) / Stellar Classification b. y-axis: Luminosity (Sun = 1)

a. x-axis: Age (Million Years) b. y-axis: Distance from Earth (Light Years)

a. x-axis: Mass (Solar Masses) b. y-axis: Radius (Solar Radii)

a. x-axis: Apparent Magnitude b. y-axis: Surface Gravity

What happens to the luminosity of stars as the surface temperatures increase?

The luminosity of stars generally increases as the surface temperature increases (for main sequence stars).

The luminosity of stars generally decreases as the surface temperature increases (for main sequence stars).

The luminosity of stars remains constant as the surface temperature increases (for main sequence stars).

The luminosity of stars fluctuates randomly as the surface temperature increases (for main sequence stars).

How will you describe the temperature of white dwarf stars?

White dwarf stars have high surface temperatures.

White dwarf stars have low surface temperatures.

White dwarf stars have moderate surface temperatures.

White dwarf stars have variable surface temperatures.

Label the seasons in both Northern and Southern Hemispheres. (Refer to the diagram showing Earth's orbit around the Sun with four positions labeled N and S. Fill in the boxes with the correct seasons for each hemisphere.)

Northern Hemisphere: Spring, Summer, Fall, Winter; Southern Hemisphere: Fall, Winter, Spring, Summer (order depends on position in orbit)

Northern Hemisphere: Summer, Fall, Winter, Spring; Southern Hemisphere: Winter, Spring, Summer, Fall (order depends on position in orbit)

Northern Hemisphere: Fall, Winter, Spring, Summer; Southern Hemisphere: Spring, Summer, Fall, Winter (order depends on position in orbit)

Northern Hemisphere: Winter, Spring, Summer, Fall; Southern Hemisphere: Summer, Fall, Winter, Spring (order depends on position in orbit)

Label the types of solar eclipse. Then, describe each type.

Total Solar Eclipse: The Moon completely covers the Sun. Partial Solar Eclipse: The Moon covers part of the Sun. Annular Solar Eclipse: The Moon covers the center of the Sun, leaving a ring-like appearance.

Total Solar Eclipse: The Moon partially covers the Sun. Partial Solar Eclipse: The Moon completely covers the Sun. Annular Solar Eclipse: The Moon is not visible at all.

Total Solar Eclipse: The Sun covers the Moon. Partial Solar Eclipse: The Sun covers part of the Moon. Annular Solar Eclipse: The Sun is completely blocked by the Moon.

Total Solar Eclipse: The Moon covers the Sun, leaving a ring. Partial Solar Eclipse: The Moon is not visible. Annular Solar Eclipse: The Moon completely covers the Sun.

Axial tilt is one of the main reasons for seasons because:

it causes different parts of Earth to receive varying amounts of sunlight throughout the year.

it changes the distance between the Earth and the Sun.

it affects the speed of Earth's rotation.

it causes the Moon to orbit the Earth.

Based on the diagram, how do scientists determine the age of the fossils?

By comparing the layers of rock in which the fossils are found

By measuring the size of the fossils

By observing the color of the fossils

By counting the number of fossils in each layer
