Explanations:The term "Eurasia" refers to the combined landmass of the continents of Europe and Asia. This term is used in geography, history, and other fields to describe the region that encompasses both continents. The continents of Europe and Asia are physically connected, forming the largest contiguous landmass on Earth. The division between Europe and Asia is primarily cultural and historical rather than geographical, as there is no natural boundary that separates the two continents.
Understanding the concept of Eurasia is important for several reasons. First, it helps in comprehending the geographical layout of the Earth, particularly the distribution of landmasses. Second, it is useful in historical and cultural studies, as the region has been a center of human civilization for thousands of years. Third, it is relevant in political and economic contexts, as the region includes many countries with significant global influence.
It is important to note that while Europe and Asia are considered separate continents, they are part of the same landmass. The term "Eurasia" is used to emphasize this connection and to highlight the shared geographical and sometimes cultural aspects of the region. The other options provided in the question, such as America and Antarctica, refer to different continents and are not related to the combined landmass of Asia and Europe.
Therefore, the correct answer to the question "Asia and Europe together is called as ...." is "Eurasia." This term accurately describes the combined landmass of the two continents and is widely recognized in geographical and historical contexts.
