Explanation:

The Earth's mantle is composed of silicate minerals rich in iron and magnesium. The core is mainly iron - nickel. The crust is made of granite (continental crust) and basalt (oceanic crust). Temporal scale refers to the time - related aspects in geological studies, geological process is the natural process that shapes the Earth's surface and interior, and spatial scale pertains to the size or extent in space in geological contexts.

1. The correct statement about Earth's layers: The Earth's mantle is made of silicate minerals rich in iron and magnesium.
2. Definitions:

• Temporal Scale: The time frame over which geological events occur.
• Geological Process: A natural process that changes the Earth's physical features.
• Spatial Scale: The size or extent of a geological feature or area.

Answer:

1. The Earth's mantle is made of silicate minerals rich in iron and magnesium.
2. Temporal Scale: The time frame over which geological events occur.

Geological Process: A natural process that changes the Earth's physical features.
Spatial Scale: The size or extent of a geological feature or area.
