What do you understand about fast and slow changes? Give suitable examples of each.? ›

In contrast, a fast chemical reaction occurs without a catalyst and is called an elementary reaction. Examples of slow reactions: Ripening of fruits, Day and night formation, Rusting of iron. The changes which take place in a short period are called fast changes.

The changes which take place in a long period of time are called slow changes whereas the changes which takes place in a short period of time are called fast changes. e.g., Slow changes - Rusting of iron, ripening of fruits, growing of trees. Fast changes - Burning of paper, blowing of balloons, bursting of crackers.

The changes that take a long duration of time to complete, are called slow changes. This duration can be in hours, days or even months. The changes that are completed in short or very short duration of time are called fast changes.

An object which takes longer time to cover a certain distance is called slow whereas another object which takes shorter time to cover the same distance is called fast.

Part 2: Examples of slow change: Rusting of iron: It is a slow change as the formation of rust is not an immediate reaction, it takes a long period of time. Ripening of fruits: It is also a slow change because the ripening of fruits takes a long time and there is also a change in the color and taste of fruits.

Slow changes cannot be felt or noticed by humans because they are gradual and do not feel like much is happening. On the other hand, fast changes happen quickly and are easier for humans to notice; for example, when someone throws a ball, it goes up into the air very high but then falls back down fast.

(b) Burning of paper, stretching of a rubber band, blowing of balloons, bursting of crackers are fast changes.

Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.

Forests succession involves change in the species structure of forest over time and one community of plant species replaces another. Succession is a series of progressive changes in the composition of an ecological community over time. Therefore; forest succession may cause the environment to change slowly.

Correct answer:

Erosion is an event that happens daily on Earth, but it happens very slowly. Erosion is the movement of the broken down materials from weathering. The dirt, plant matter, rocks, and other materials are moved to a new location, and new landforms are created while others are destroyed or changed.

Examples of moving object

An auto-rickshaw can move slow or fast depending upon the traffic, an auto-rickshaw can move faster than a bicycle but an aeroplane can move faster than the auto-rickshaw, how can we decide if one object is moving faster or slower than the other?

Answer: Slow-moving: Turtle, Sloth, Tortoise, Jellyfish, Snail, Starfish, Koala, Seahorse, Elephant, etc. Fast-moving: Flying rockets, Bouncing ping-pong balls, Tennis balls, Balancing pencils, Cheetas, Airplanes, Trains, Peregrine falcon, Black marlin, etc.

The changes which take place in a long period of time are called slow changes. Example: Rusting of iron, formation of day and night, ripening of fruits, growing of trees are slow changes. The changes which take place in a short period of time are called fast changes.

Slow and Slowly as Adverbs:

The cars on the road are all moving slow/slowly. She stood up slow/slowly after falling off her bike. Her son ate so slow/slowly that it was bedtime when he was finally finished. The computer was running so slow/slowly that he didn't finish his homework on time.

Here are some examples of both slow and spontaneous processes: Slow processes: The formation of a fossil from the remains of a living organism, which can take millions of years. The growth of a tree from a seed to a mature plant, which can take decades or even centuries.

Weathering can happen in many different ways and usually happens slowly over time. Roots of plants and trees can grow into rocks and eventually split them apart. Some children may notice when plants or tree roots break through sidewalks or concrete. This is one example of weathering.

Hence, rusting of iron is a slow natural chemical change.
