1.

Which of the following processes cause a sedimentary rock to change into a metamorphic rock?
- A.
  
  Weathering and erosion
- B.
  
  Heat and pressure
- C.
  
  Cooling and hardening
- D.
  
  Melting
Correct Answer
B. Heat and pressure

Explanation
Heat and pressure are the processes that cause a sedimentary rock to change into a metamorphic rock. When sedimentary rocks are subjected to high temperatures and pressures deep within the Earth's crust, their mineral composition and texture undergo significant changes. The heat and pressure cause the minerals in the rock to recrystallize, resulting in the formation of new minerals and a more compact, crystalline structure. This process, known as metamorphism, can occur due to tectonic forces, burial, or contact with hot fluids.

Which type of rock is made of hardened magma?
- A.
  
  Igneous
- B.
  
  Sedimentary
- C.
  
  Metamorphic
- D.
  
  Fossi
Correct Answer
A. Igneous

Explanation
Igneous rock is formed from hardened magma. Magma is molten rock that is found beneath the Earth's surface. When magma cools and solidifies, it forms igneous rock. This process can occur either underground, resulting in intrusive igneous rock, or on the Earth's surface, resulting in extrusive igneous rock. Igneous rocks are characterized by their crystalline structure and can have a range of compositions, depending on the minerals present in the original magma.

Which statement about the rock cycle is true?
- A.
  
  Rocks never change
- B.
  
  Heat and pressure form igenous rock
- C.
  
  Rocks can only change from igneous to sedimentary
- D.
  
  Rocks constantly change into other rocks
Correct Answer
D. Rocks constantly change into other rocks

Explanation
The rock cycle is a continuous process where rocks are constantly changing into different types through various geological processes such as weathering, erosion, heat, pressure, and melting. This means that rocks are not static and can transform from one type to another over time.

In which soil layer do most plants grow?
- A.
  
  Topsoil
- B.
  
  Subsoil
- C.
  
  Weathered rock
- D.
  
  Solid rock
Correct Answer
A. Topsoil

Explanation
Most plants grow in the topsoil layer because it is the uppermost layer of soil that contains the highest concentration of organic matter, nutrients, and moisture. This layer is rich in humus, which provides essential nutrients for plant growth, and it has a loose and crumbly texture that allows roots to penetrate easily. Additionally, the topsoil layer is where most of the biological activity occurs, including the decomposition of organic matter and the presence of beneficial microorganisms that aid in nutrient cycling.

Melted rock inside the earth is called ___________________. When it reaches the earth's surface it is called ___________________.
- A.
  
  Fault, volcano
- B.
  
  Crust, lava
- C.
  
  Lava, magma
- D.
  
  Magma; lava
Correct Answer
D. Magma; lava

Explanation
Melted rock inside the earth is called magma. When it reaches the earth's surface it is called lava.

Waves of energy caused by movements of rock that is felt on Earth's surface are called
- A.
  
  Volcanoes
- B.
  
  Earthquakes
- C.
  
  Twisters
- D.
  
  Landslide
Correct Answer
B. Earthquakes

Explanation
Waves of energy caused by movements of rock that is felt on Earth's surface are called earthquakes. Earthquakes occur when there is a sudden release of energy in the Earth's crust, resulting in seismic waves that shake the ground. These waves can cause significant damage and destruction to buildings and infrastructure. Volcanoes, twisters, and landslides are all natural phenomena that can also cause destruction, but they are not specifically related to the movements of rock that cause earthquakes.

Roots of a plant grow inside the cracks in a rock. Water seeps into the crack, freezes, and the crack widens. What is this an example of?
- A.
  
  Erosion
- B.
  
  Deposition
- C.
  
  Weathering
- D.
  
  Raining
Correct Answer
C. Weathering

Explanation
This is an example of weathering. Weathering refers to the process by which rocks and minerals are broken down into smaller pieces by various physical, chemical, and biological processes. In this case, the water seeping into the crack causes freeze-thaw cycles, where the water freezes and expands, widening the crack. Over time, this repeated cycle of freezing and thawing causes the crack to widen further, eventually allowing roots to grow inside.

When loose sediments are carried away by water, dropped, and deposited in new places it is called ______________
- A.
  
  Deposition
- B.
  
  Erosion
- C.
  
  Weathering
- D.
  
  Glaciers
Correct Answer
A. Deposition

Explanation
Deposition refers to the process in which loose sediments are transported by water, then dropped and deposited in new locations. This can occur in various water bodies such as rivers, lakes, and oceans. During deposition, the sediments settle and accumulate, forming new landforms or layers of sedimentary rocks over time. This process is essential in shaping the Earth's surface and creating various geological features.

Two examples of rapid changes to earth's surface are:
- A.
  
  Earthquakes and landslides
- B.
  
  Weathering and erosion
- C.
  
  Glaciers and melting
- D.
  
  Wind and rain
Correct Answer
A. Earthquakes and landslides

Explanation
Earthquakes and landslides are both examples of rapid changes to the Earth's surface. Earthquakes occur when there is a sudden release of energy in the Earth's crust, causing the ground to shake and potentially leading to the formation of new landforms or the destruction of existing ones. Landslides, on the other hand, involve the downward movement of a mass of soil, rocks, or debris along a slope. Both earthquakes and landslides can cause significant changes to the Earth's surface in a short amount of time.
