• 😀 Magma erupts from a volcano as lava.
• 😀 Flowers in plants eventually turn into fruits.
• 😀 The lens of the eye focuses light onto the retina.

• 😀 Mammals are the only animals listed that do not lay eggs.
• 😀 Freezing is the method to lower the temperature of a substance.
• 😀 A black hole is located at the center of galaxies.
• 😀 Microorganisms serve as the last stage in the food chain cycle.
• 😀 A lunar eclipse occurs when the Earth is between the Sun and the Moon.
• 😀 The circulatory system is responsible for carrying oxygen throughout the body.
• 😀 Reproduction happens when the pistol of a plant is fertilized.
• 😀 Earth is called the 'Big Blue Marble' because 70% of its surface is covered by water.
• 😀 Paracity is observed when a cloth is used to wipe a wet surface.
• 😀 Deforestation is a major cause of flooding.
• 😀 Water is denser than oil, which is why oil floats on water.
• 😀 An increase in carnivores decreases the number of plants on an island.

What is the main energy source needed for daily activities?

The main energy source needed for daily activities is rice.

What do satellites like the moon revolve around?

Satellites like the moon revolve around planets.

Which body part is responsible for sensing texture?

The skin is responsible for sensing texture.

What type of soil has the loosest particles?

Sandy soil has the loosest particles.

What landform erupts with magma that becomes lava?

A volcano erupts with magma that becomes lava.

What part of the plant turns into a fruit?

The flower of the plant eventually turns into a fruit.

What part of the eye focuses light?

The lens focuses the light that the eye captures.

What type of weather commonly results when clouds occupy the sky?

When clouds occupy the sky, it commonly results in rainy weather.

Why is Earth often called the 'Big Blue Marble'?

Earth is called the 'Big Blue Marble' because 70% of its surface is covered by water.

What property of a cloth is observed when it wipes off a wet surface?

The property observed is porosity when a cloth is used to wipe off a wet surface.

What is a primary cause of flooding?

Deforestation is a primary cause of flooding.

Why does oil float on water?

Oil floats on water because water is denser than oil.

What happens when the number of carnivores increases on an island?

When the number of carnivores increases on an island, the number of plants decreases.

Which of the following is true about gases?

Gases can be compressed and follow the shape of their container.

What illness may result from eating too much salt?

Eating too much salt may lead to kidney failure.

What type of rock is formed when lava cools off?

Extrusive igneous rocks are formed when lava cools off.

Where does light move fastest?

Light moves fastest in a vacuum.

In scissors, where is the effort applied to cut paper?

The effort is applied to the scissors' handle to cut paper.

What causes tides in the ocean?

Tides are primarily caused by the moon's gravity.

What process helps mammals cool off and regulate body heat?

Perspiration helps mammals cool off and regulate body heat.
