True, if you have Titanfall installed via EA Desktop and you buy it through Steam, you will have to reinstall it through Steam.

Explanation:

This is because Steam and EA Desktop are separate platforms, and games purchased on one platform cannot be directly transferred to the other. To play Titanfall through Steam, you will need to download and install it using the Steam client.

Additionally, even though Titanfall is the same game, the version available on EA Desktop and the version available on Steam may have some differences in terms of features or updates. This means that the game installation files for the EA Desktop version may not be compatible with the Steam version, and vice versa. Furthermore, the game save data for the EA Desktop version may not be compatible with the Steam version either, which means that you may need to start the game from scratch if you switch from one platform to the other. Therefore, it is important to keep in mind that purchasing a game on one platform does not necessarily mean that you will have access to the same version of the game on another platform, and you may need to reinstall and start from scratch if you switch platforms.

True. If you have Titanfall installed via EA Desktop and decide to purchase it through Steam, you will need to reinstall it through Steam. This is because EA Desktop and Steam are separate platforms with different installation paths, game libraries, and management systems.


1. Purchase Titanfall on Steam: To start the process, buy the game through your Steam account.

2. Download and install Titanfall on Steam: After purchasing, you will need to download and install Titanfall through Steam. This will create a new installation separate from the one on EA Desktop.

3. Launch Titanfall through Steam: Once the game is installed, you can launch and play Titanfall using Steam. Your game progress and achievements may not carry over between platforms, so you may need to start fresh or find a way to transfer your saved data.

4. Uninstall Titanfall from EA Desktop (optional): If you no longer want to keep the EA Desktop version of Titanfall, you can uninstall it to save storage space on your computer.

Remember to keep your game saves and data in mind when switching between platforms, as progress may not be automatically transferred.

Photochemical smog is formed when sunlight interacts with certain air pollutants, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), in the presence of sunlight.

Therefore, it is most likely to occur in an urban area in a high-sunshine location.

In an urban area, there are typically higher concentrations of vehicles, industrial emissions, and other human activities that release NOx and VOCs into the air. These pollutants can accumulate in the urban atmosphere, and when exposed to sunlight, they can undergo photochemical reactions that result in the formation of photochemical smog.

High levels of sunlight are necessary for the formation of photochemical smog because the reactions that produce smog require energy from sunlight to occur. In rural areas or low-sunshine locations, the availability of sunlight may be limited, which reduces the likelihood of photochemical smog formation. However, in urban areas with high levels of sunlight, combined with significant emissions of NOx and VOCs, the conditions for photochemical smog formation are more favorable.
