A narrow strip of land that runs parallel to a coast is known as a coastal plain or coastal strip. This area is typically characterized by flat, low-lying terrain and is often influenced by tidal activities. Coastal plains can support various ecosystems and human developments, including cities and agriculture, due to their proximity to the ocean.

Temperatures are cooler in the mountains than in the valleys primarily due to the decrease in atmospheric pressure and density with elevation. As altitude increases, the air becomes thinner and less able to hold heat, leading to lower temperatures. Additionally, the process of adiabatic cooling occurs when air rises, expands, and cools, further contributing to the cooler mountain climate compared to the warmer, denser air in the valleys.

Lowlands and plains are primarily found in the temperate, tropical, and polar ecozones. These areas typically feature flat or gently rolling terrain, allowing for extensive agricultural and settlement opportunities. Examples include the Great Plains in North America, the Pampas in Argentina, and the lowland rainforests of the Amazon Basin. Additionally, coastal plains and river valleys are also significant lowland regions across various ecozones.

A large unbroken area of land is commonly referred to as a "continent" when it encompasses a significant mass of land. In a more localized context, it can also be described as a "plateau," "plain," or "expanse," depending on the geographical features of the area. These terms highlight the continuity and lack of significant interruptions in the land.

The Midwest region of the United States is often characterized by its flat grassy plains, particularly in areas known as the Great Plains.
