Το μεγαλύτερο μέρος της Γης καλύπτει ο:
Correct Answer
B. μανδύας.
Explanation
The correct answer is "μανδύας" because it is the Greek word for "cloak" or "mantle" which is the closest translation to the given word "φλοιός". The other options "εξωτερικός πυρήνας" and "εσωτερικός πυρήνας" mean "external core" and "internal core" respectively, which are unrelated to the given word. Therefore, "μανδύας" is the most appropriate and logical choice based on the context.
2.
Τα μέταλλα που επικρατούν στον πυρήνα της Γης είναι:
Correct Answer
D. ο σίδηρος και το νικέλιο.
Explanation
The correct answer is "ο σίδηρος και το νικέλιο." This is because the question is asking for the elements that are included in the alloy called "Gamma ησφ είναι." The options given include different combinations of iron (σίδηρος), copper (χαλκός), and nickel (νικέλιο). By eliminating the other options, it can be determined that the correct combination is iron and nickel.
3.
Η λιθόσφαιρα αποτελείται από:
Correct Answer
C. το φλοιό και το ανώτερο τμήμα του μανδύα.
Explanation
The correct answer is "το φλοιό και το ανώτερο τμήμα του μανδύα." This is because the question is asking for what parts make up the bark of a tree. The options "το φλοιό" (the bark) and "το ανώτερο τμήμα του μανδύα" (the upper part of the bark) are both correct components of the bark. The other options mentioned, "το μανδύα" (the mantle) and "τον εξωτερικό πυρήνα" (the outer core), are not part of the bark.

Οι μεγάλες λιθοσφαιρικές πλάκες είναι:
Correct Answer
A. 7
5.
Οι λιθοσφαιρικές πλάκες μπορεί:
Correct Answer
D. να κάνουν όλα τα παραπάνω.
Explanation
The correct answer is "να κάνουν όλα τα παραπάνω." This means "to do all of the above." The question is asking for the possible outcomes of a certain situation, and the correct answer states that all of the options listed (converging, diverging, moving laterally) are possible outcomes.

Στην εικόνα φαίνεται η κίνηση δύο λιθοσφαιρικών πλακών. Ηφαίστειο μπορεί να σχηματιστεί στη θέση:
Correct Answer
D. Δ.
7.
Η δημιουργία των μεγάλων οροσειρών οφείλεται:
Correct Answer
A. στη σύγκλιση των λιθοσφαιρικών πλακών.
Explanation
The correct answer is "στη σύγκλιση των λιθοσφαιρικών πλακών." This is because the term "σύγκλιση" means convergence in Greek, and it refers to the process of two lithospheric plates moving towards each other and colliding. This collision can lead to various geological phenomena such as the formation of mountains, earthquakes, and volcanic activity. Therefore, the convergence of lithospheric plates is a significant factor in shaping the Earth's surface and is the most appropriate explanation in this context.
8.
Η δημιουργία των μεσοωκεάνιων ραχών οφείλεται:
Correct Answer
B. στην απόκλιση των λιθοσφαιρικών πλακών.
Explanation
The correct answer is "στην απόκλιση των λιθοσφαιρικών πλακών." This is because the term "απόκλιση" translates to "divergence" in English, which refers to the movement of tectonic plates away from each other. This movement creates rifts and gaps between the plates, which can lead to the formation of new crust and volcanic activity. Therefore, the correct answer indicates that the convergence of lithospheric plates is responsible for the given phenomenon.
9.
Ένα ηφαίστειο μπορεί να δημιουργηθεί:
Correct Answer
C. είτε με τη σύγκλιση είτε με την απόκλιση δύο λιθοσφαιρικών πλακών.
Explanation
The correct answer is "είτε με τη σύγκλιση είτε με την απόκλιση δύο λιθοσφαιρικών πλακών." This means that earthquakes can occur either during the convergence or divergence of two lithospheric plates. This is because the movement of these plates can cause stress and build up of energy, which is released in the form of an earthquake. So, whether the plates are colliding or moving apart, earthquakes can still occur.
10.
Οι θερμές κηλίδες (hot spots) είναι:
Correct Answer
D. ηφαιστειακά νησιά στο μέσο μιας λιθοσφαιρικής πλάκας.
Explanation
Hot spots are volcanic areas that are located in the middle of a tectonic plate, away from plate boundaries. This is in contrast to volcanic islands that are located at the boundaries of two tectonic plates. Therefore, the correct answer is "ηφαιστειακά νησιά στο μέσο μιας λιθοσφαιρικής πλάκας" which translates to "volcanic islands in the middle of a tectonic plate".
