Catalonia’s Geography, Climate, Resources, and Cultural Heritage
1. Territory and Natural Resources
1.1 Territorial Configuration
Catalonia, characterized by a 552km Mediterranean coastline and a complex 31,130 sq km terrain, presents a diverse landscape. From coastal plains to mountainous regions with altitudes exceeding 5% above sea level, the territory features a mix of plains, plateaus, cliffs, depressions, hills, and old alpine massifs. The proximity of mountains and sea creates a rugged coastline, leaving narrow coastal plains. The sea plays a crucial role

Main Features of Peninsular and Insular Relief
The Geographical Area of Spain: Spain is a medium-sized European state located in the temperate northern hemisphere. It comprises a peninsula, the Mediterranean archipelago (Balearic Islands), the Atlantic archipelago (Canary Islands), Ceuta, and Melilla (in North Africa).
Peninsular Relief: Spanish relief configuration has three basic features:
The massive form is given by the great width of the peninsula

Andalusian Atlantic Coast
The Andalusian Atlantic coast stretches from the Portuguese border to the Rock of Gibraltar and the Bay of Cádiz. Alluvial deposits from rivers have created low-lying coastal plains with small sand dunes, similar to those found along the coasts of Huelva and Cádiz. Ocean currents accumulate sand in places, forming littoral arrows (coastal formations built up from accumulated material resting on a rocky coast or island).
If these sandy formations run parallel to the coast,

Determining Seed Maturity: Lab Methods
1. Dry Weight
Maximum dry weight indicates maturity.
2. Moisture Content
Some fruits lose moisture during maturation.
3. Analysis and X-ray Method
Chemical analysis and X-ray imaging can assess maturity.
Determining Seed Maturity: Field Methods
1. Fruit Weight
Fruit weight generally decreases with maturity.
2. Seed Contents
Mature seeds have a firm, white endosperm and a well-developed embryo.
3. Fruit Color and Odor
Slight variations in color and odor can indicate maturity.
