Soil and water

The idea

Soil (land) heats up faster than water and also cools down faster than water.

At the beach

Palden says, "During the day, the sand near the beach is hotter than the water in the sea. At night the sand is cooler than the water."

Which one do you think heats up faster in the Sun?

• Soil
• Water
• Both heat up at the same rate

Sun on two cups

Press the button. Look at the two thermometers. Then press again when the Sun goes away.

Soil is quick

The soil got hotter than the water in the same time. When the Sun went away, the soil also cooled more than the water. Soil changes its temperature faster, both ways.

Soil (land) heats up faster than water and also cools down faster than water.

• In the Sun | When the Sun goes away
• Soil heats up faster | Soil cools down faster
• Water heats up slower | Water cools down slower

Notes

Soil (land) heats up faster than water and also cools down faster than water.

Check yourself

In the same time in the Sun, which gets hotter?

When the Sun goes away, which cools down faster?

During the day at a beach, the sand is hotter than the sea water because …

At night, the sand near the beach is cooler than the water because …

• Soil — correct. Yes!
• Water. Water heats up more slowly than soil.
• They always stay equal. In the same time, soil gets hotter than water.
• Water. Water cools down more slowly than soil.
• Soil — correct. Yes!
• Neither one cools. Both lose heat, and soil loses it faster.
• water heats up faster than soil. It is the other way round. Soil heats up faster.
• sand is made of salt water. Sand is not salt water. It is land, and land heats up faster.
• soil heats up faster than water — correct. Yes!
• soil cools down faster than water — correct. Yes!
• soil cools down slower than water. Soil cools down faster, so it is cooler than the sea at night.
• the Sun shines on the sand at night. There is no sunlight at night.
