Earth Science and Biology Concepts

The video answers kids' questions about how years and days are determined by Earth's orbit and rotation, how food travels to the stomach via the esophagus, and why some people experience lactose intolerance. It explains Earth's tilt and its effect on seasons, the role of the diaphragm in breathing and coughing, and the digestive system's function in processing food. The video concludes with a thank you to viewers and encourages them to send more questions.

What determines the length of a year on Earth?

• The Earth's rotation on its axis

• The distance from the Sun

• The Earth's orbit around the Sun

• The tilt of the Earth's axis

Why do we experience different seasons on Earth?

• The Earth's distance from the Sun changes

• The Earth's tilt on its axis

• The Earth's rotation speed varies

• The Sun's temperature changes

What causes day and night on Earth?

• The Moon's phases

• The Sun's movement

• The Earth's rotation on its axis

• The Earth's orbit around the Sun

What is the role of the esophagus in the digestive system?

• It absorbs nutrients from food

• It connects the mouth to the stomach

• It stores food temporarily

• It breaks down food into energy

What is the function of the trachea?

• To digest food

• To carry air to the lungs

• To transport food to the stomach

• To pump blood

What happens when food goes down the 'wrong tube'?

• It enters the trachea

• It enters the esophagus

• It goes directly to the stomach

• It gets stuck in the mouth

What muscle helps us breathe by moving air in and out of the lungs?

• The trachea

• The esophagus

• The diaphragm

• The heart

Why might some adults have trouble digesting milk?

• They produce less lactase

• They drink too much milk

• They have a smaller stomach

• They eat too much cheese

What is lactase's role in the digestive system?

• To store energy

• To absorb vitamins

• To break down milk

• To break down proteins

What can help people who are lactose intolerant enjoy dairy products?

• Avoiding all dairy

• Taking lactase supplements

• Drinking more water

• Eating more vegetables
