Answer:
Greece is dominated by hills and mountains, with only the northern part being a relatively flat plain, and it also has thousands of islands varying in size.
Step-by-step explanation:
Greece is a country that is predominantly composed of hills and mountains. It is only the northern part of the country that is a relatively large and flat plain. Also, Greece has thousands of islands, most of which are rocky and very dry. Such (generalized) physical features of Greece mean that most of the country is not suitable for agriculture, but the only part, the northern one, is heavily exploited for this purpose.
Even though it is a small country, Greece has a very long coastline, and this is due to the very rugged coastline. The country is also tectonically highly active, and this contributes to regular earthquake activity. Also, the majority of the country (mountains and hills) is growing gradually in elevation, while its northtern flat plain is gradually sinking and is on the way to create a depression.
