Question

Accepted Answer

### 1.
# Explanation:
## Step1: Define contour interval
Contour interval is the vertical distance between adjacent contour lines on a topographic map. It is set by the map - maker based on the area's relief and the map's scale. Usually, it is determined by dividing the total vertical range of the area by the number of contour lines that can be reasonably shown on the map for clarity.
# Answer:
The contour interval is the fixed vertical distance between adjacent contour lines on a topographic map, decided by the map - maker considering the area's relief and map scale.

### 2.
# Brief Explanations:
Hawaii is a volcanic island chain. Its topography is characterized by volcanic mountains, steep slopes near the volcanoes, and coastal plains. A profile with a central high - elevation area (volcanic peak) and sloping downwards to the coast would most likely match.
# Answer:
A profile with a central peak (volcanic mountain) and sloping down to the coastal areas.

### 3.
# Explanation:
## Step1: Locate bolded locations
Without the actual map, we assume one would use a map key or legend to identify the latitude and longitude grid lines. Then, for each bolded location, one would find the intersection of the latitude and longitude lines closest to the location.
## Step2: Record coordinates
Read the values of the latitude and longitude lines at the intersection and record them as the coordinates of the location.
# Answer:
Without the actual map, the specific coordinates cannot be provided. But the process is to use the map grid and read the latitude and longitude values at the location's intersection.

### 4.
# Brief Explanations:
A. Quartz gets its crystal form from the arrangement of silicon and oxygen atoms in a tetrahedral structure that repeats in a regular pattern during crystallization.
B. Quartz is formed through igneous processes (cooling and solidification of magma or lava), metamorphic processes (alteration of existing rocks under high - pressure and high - temperature conditions), and sedimentary processes (precipitation from water solutions).
C. Quartz belongs to the silicate mineral group as it contains silicon and oxygen.
D. In everyday life, quartz is used in watches (quartz crystals for timekeeping), glass - making, and as an abrasive in sandpaper.
# Answer:
A. From the arrangement of silicon - oxygen tetrahedra during crystallization.
B. Through igneous, metamorphic, and sedimentary processes.
C. Silicate mineral group.
D. In watches, glass - making, and as an abrasive.

### 5.
# Brief Explanations:
The rock cycle is powered by the Earth's internal heat (from radioactive decay in the Earth's interior, which drives processes like melting of rocks to form magma) and solar energy (which drives weathering, erosion, and sediment transport on the Earth's surface).
# Answer:
Earth's internal heat and solar energy.

### 6.
# Brief Explanations:
Rocks are classified based on their origin into three main types: igneous (formed from cooling and solidification of magma or lava), sedimentary (formed from the accumulation and compaction of sediments), and metamorphic (formed from the alteration of existing rocks under high - pressure and high - temperature conditions).
# Answer:
Based on origin into igneous, sedimentary, and metamorphic rocks.

### 7.
# Brief Explanations:
Igneous rocks can be coarse - grained (if they cool slowly deep within the Earth) or fine - grained (if they cool quickly on the Earth's surface). They often have a crystalline texture. Sedimentary rocks usually have a layered or stratified appearance and may contain fossils. Metamorphic rocks can have a foliated (layered or banded) or non - foliated texture, depending on the type of metamorphism.
# Answer:
Igneous: Crystalline texture, variable grain size. Sedimentary: Layered, may have fossils. Metamorphic: Foliated or non - foliated texture.
