Question 1:

Image: Four trees showing different seasons (spring, summer, autumn, winter).
Description: "The weather pattern of an area over a long period of time."
Options:
- A. Climate
- B. Global grid
- C. Weather

#### Solution:
- Climate refers to the average weather conditions of a region over a long period (typically 30 years or more). It includes patterns of temperature, precipitation, humidity, wind, etc.
- Weather refers to short-term atmospheric conditions, such as temperature, humidity, cloudiness, wind, rain, etc., at a specific time and place.
- Global grid refers to the network of latitude and longitude lines used to locate points on Earth's surface.

Since the question asks about the "weather pattern of an area over a long period of time," the correct answer is A. Climate.

Question 2:

Image: A globe with horizontal lines running east to west.
Description: "Lines that run east to west around the earth."
Options:
- A. Climate
- B. Degree
- C. Longitude
- D. Latitude

#### Solution:
- Latitude refers to the angular distance of a point north or south of the equator, measured in degrees. These are the horizontal lines running east to west on a globe.
- Longitude refers to the angular distance of a point east or west of the prime meridian, measured in degrees. These are the vertical lines running north to south on a globe.
- Degree is a unit of measurement for angles, but it does not describe lines on the Earth.
- Climate is unrelated to the description of lines on the Earth.

Since the question asks about lines running east to west, the correct answer is D. Latitude.

Question 3:

Image: A globe with vertical lines running north to south.
Description: "Lines that run north to south around the earth."
Options:
- A. Degree
- B. Latitude
- C. Climate
- D. Longitude

#### Solution:
- Longitude refers to the angular distance of a point east or west of the prime meridian, measured in degrees. These are the vertical lines running north to south on a globe.
- Latitude refers to the angular distance of a point north or south of the equator, measured in degrees. These are the horizontal lines running east to west on a globe.
- Degree is a unit of measurement for angles, but it does not describe lines on the Earth.
- Climate is unrelated to the description of lines on the Earth.

Since the question asks about lines running north to south, the correct answer is D. Longitude.

Question 4:

Image: A globe with a grid formed by intersecting lines.
Description: "Pattern formed on a map by the crossing of parallels and meridians."
Options:
- A. Climate
- B. Degree
- C. Global grid
- D. Longitude

#### Solution:
- Global grid refers to the network formed by the intersection of latitude (parallels) and longitude (meridians) lines on a map or globe. This grid helps in locating points on Earth's surface.
- Climate is unrelated to the description of lines or grids.
- Degree is a unit of measurement for angles, but it does not describe the pattern formed by the grid.
- Longitude refers only to the vertical lines running north to south and does not describe the entire grid pattern.

Since the question asks about the pattern formed by the crossing of parallels and meridians, the correct answer is C. Global grid.
