Choose the correct sequence of regions according in ascending order of their temperature.

Options

A. Polar areas `to` Temperate areas `to` sub tropical areas `to` Tropical areas
B. Equator `to` Timber line `to` Tropical deserts
C. Deep sea hydrothermal vents `to` Tropical deserts `to` mountain top
D. Polar areas `to` Tropical deserts `to` Mountain top `to` Timber line

Answer

To determine the correct sequence of regions according to ascending order of their temperature, we need to analyze the temperature characteristics of different geographical regions on Earth. Here’s a step-by-step solution:

### Step 1: Understand the Temperature Zones
- **Polar Regions**: These regions are located at the North and South Poles and are characterized by extremely low temperatures. The climate here is cold year-round.
- **Temperate Regions**: These areas are located between the polar and tropical regions. They experience moderate temperatures, which can vary significantly between seasons but are generally warmer than polar regions.
- **Tropical Regions**: These regions are near the equator and are known for their high temperatures throughout the year. They typically have warm climates with little variation in temperature.

### Step 2: Arrange the Regions by Temperature
Now that we have identified the characteristics of each region, we can arrange them in ascending order of temperature:
1. **Polar Regions**: Coldest temperatures
2. **Temperate Regions**: Moderate temperatures
3. **Tropical Regions**: Hottest temperatures

### Final Sequence
Thus, the correct sequence of regions according to ascending order of their temperature is:
- **Polar Regions < Temperate Regions < Tropical Regions**
