During a Science class on weather forecasting, the teacher explained that the relative humidity of the air plays a key role in cloud formation and rain prediction. The relative humidity of the air is the ratio between the amount of water vapor present in the air and the maximum amount the air can hold at that temperature. The teacher presented the following challenge to the students: 'Considering a region where the temperature is 30°C and the relative humidity of the air is 50%, and knowing that the dew point is the temperature at which the air, at constant pressure, becomes saturated with water vapor, forming dew drops or, if the temperature is below 0°C, ice crystals, calculate the dew point in this situation. Also, explain how knowledge of the dew point can be useful in predicting fog formation, considering that the temperature can vary throughout the day.'Answer sheet:

Exotic and invasive species are those that, due to human transportation, are taken to other ecosystems and end up becoming a non-native species, which can affect local biodiversity. For example, the red swamp crayfish (Procambarus clarkii) was introduced in Brazil in the mid-20th century for food production. What is the biggest risk of this species to Brazilian biodiversity?

Natural phenomena can be considered as extremely important events for our planet, as they influence the climate and the life of the species that exist on it. For example, rains are necessary to keep the rivers and lakes full and thus ensure drinking water for all living beings that depend on it to survive. Which of the following is an example of a natural phenomenon that contributes to the balance of the Earth?

The ozone layer, located in the stratosphere, is responsible for filtering most of the ultraviolet radiation emitted by the Sun. Its role is crucial in protecting life on Earth, as excessive exposure to this radiation can cause serious damage to the skin and contribute to the development of skin cancer. However, the action of chemicals released into the atmosphere, such as chlorofluorocarbons (CFCs), has led to a process of ozone layer depletion, making it thinner and less efficient. Considering this context, answer: 1. Explain what CFCs are and how they are related to the destruction of the ozone layer. 2. Discuss the possible consequences for the planet if the depletion of the ozone layer continues at the current rate, considering the interactions between the ozone layer and the different terrestrial and marine ecosystems.
