1. Forecast - a) a report saying what the weather is likely to be like.
To understand this, let's break down the word "forecast." "Fore" means before, and "cast" means to predict or estimate. So, a forecast is a prediction or estimation made before something happens. In the case of weather, a forecast is a report that tells us what the weather is likely to be like in the future. Weather forecasters use scientific data and tools to analyze atmospheric conditions and make predictions about the upcoming weather. These forecasts are important because they help us plan our activities, such as deciding what to wear or whether to bring an umbrella.

2. Sunshine - d) the light and heat that come from the sun.
Sunshine refers to the light and heat that we receive from the sun. The sun is a massive ball of gas that emits energy, including light and heat. When the sun's rays reach the Earth's surface, they provide us with warmth and light. Sunshine is essential for life on Earth, as it helps plants grow, provides us with vitamin D, and affects the Earth's climate. We experience sunshine during the day when the sun is visible in the sky.

3. Lightning - e) a sudden flash of light in the sky during a storm.
Lightning is a sudden flash of light that we see in the sky during a storm. It occurs when there is a buildup of electric charge within a thunderstorm cloud. The charges separate, with positive charges accumulating near the top of the cloud and negative charges gathering near the bottom. When the difference in charge becomes large enough, a rapid discharge of electricity happens, creating a bright flash of light we call lightning. It happens quickly and can be followed by thunder.

4. Thunder - c) a loud, rumbling noise that follows a flash of lightning.
Thunder is the loud, rumbling noise that we hear after seeing a flash of lightning. It occurs due to the rapid heating and expansion of the air surrounding the lightning bolt. When lightning discharges, it rapidly heats the air to around 30,000 Kelvin (53,540 degrees Fahrenheit), making it expand rapidly. This rapid expansion creates a shock wave that travels through the air, resulting in the sound we perceive as thunder. The distance between us and the lightning can be estimated by counting the number of seconds between the flash of lightning and the sound of thunder.
