Solve this and I’ll give u 5 stars and brainleist
Darina [25.2K]

Answer:

  • notice: temperature rises quickly at sunrise, and drops before sunset
  • wonder: whether this location is shaded by mountains later in the day

Step-by-step explanation:

<u>notice</u>

The temperature starts off below zero in the early morning and stays cold until the sun comes up. Then it warms rapidly to an above zero temperature that peaks in early afternoon. Once the sun gets lower, the temperature starts cooling off again. (The daily temperature range of 25-27 degrees is pretty typical for partly-cloudy sky conditions and stable weather.)

<u>wonder</u>

We wonder if this isn't a location that is on the east- or north-side of a mountain, or in a mountain valley, where the sun hits it early and is shaded later in the day. (The topo map attached seems to show it is in such a location.)
