1. Tulips
The Tulip is the most popular of the spring-flowering bulbs. It also offers the greatest variety in color, shape, and form of any bulb. Tulips typically bear cup-shaped flowers in almost every shade but true blue. They can be double or single, fringed or twisted, perfumed or nonscented.

2. Penguins
The penguin's body is adapted for swimming. Its body is fusiform (tapered at both ends) and streamlined. A penguin has a large head, short neck, and elongated body. The legs and webbed feet are set far back on the body, which gives penguins their upright posture on land.

3. Desert
A desert is a barren area of landscape where little precipitation occurs and consequently living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one third of the land surface of the world is arid or semi-arid.

4. Light House
A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses, and to serve as a navigational aid for maritime pilots at sea or on inland waterways.
