Earth Science Overview Quiz

Study Notes

Earth Science

Definition: Study of Earth’s structure, properties, processes, and changes over time.
Key Areas:
- Geology: Study of rocks, minerals, and Earth's interior.
- Meteorology: Study of weather and climate.
- Oceanography: Study of oceans and marine life.
- Astronomy: Study of celestial bodies beyond Earth.
Earth's Layers:
- Crust: Outermost layer, solid rock.
- Mantle: Thick layer of semi-solid rock; convection currents occur here.
- Outer Core: Liquid layer composed of iron and nickel.
- Inner Core: Solid innermost layer, extremely hot.
Plate Tectonics:
- Earth's lithosphere divided into tectonic plates.
- Movement causes earthquakes, volcanic eruptions, and mountain formation.
Weather vs. Climate:
- Weather: Short-term atmospheric conditions.
- Climate: Long-term average of weather patterns in a region.
Natural Resources:
- Renewable (solar, wind) and non-renewable (coal, oil) resources.
- Importance of conservation and sustainability.

Plant and Animal Cells

Cell Theory:
- All living organisms are composed of cells.
- The cell is the basic unit of life.
- All cells arise from pre-existing cells.
Plant Cells:
- Cell Wall: Rigid outer layer; provides structure and support.
- Chloroplasts: Site of photosynthesis; contains chlorophyll.
- Large Central Vacuole: Storage for nutrients, waste products, and contributes to turgor pressure.
- Shape: Generally rectangular or box-like.
Animal Cells:
- Cell Membrane: Flexible outer layer; regulates entry/exit of substances.
- Centrioles: Involved in cell division.
- Lysosomes: Contain enzymes for digestion and waste removal.
- Shape: Irregular and varied.
Common Organelles in Both:
- Nucleus: Control center containing DNA.
- Mitochondria: Energy production (ATP).
- Ribosomes: Protein synthesis.
- Endoplasmic Reticulum (ER): Synthesizes proteins (rough ER) and lipids (smooth ER).
- Golgi Apparatus: Modifies and packages proteins and lipids for distribution.
Differences Between Plant and Animal Cells:
- Presence of cell wall and chloroplasts in plant cells.
- Larger central vacuole in plant cells.
- Centrioles present in animal cells, absent in plant cells.

Earth Science

The study of Earth's composition, processes, and changes over time.
Key areas include geology, meteorology, oceanography, and astronomy.
Earth's layers consist of the crust, mantle, outer core, and inner core.
The crust is the thin, solid outermost layer, while the mantle is a thick layer of semi-solid rock where convection currents drive plate tectonics.
The outer core is liquid, composed of iron and nickel, while the inner core is solid and extremely hot.
Plate tectonics is the theory that Earth's lithosphere is divided into plates that move, causing earthquakes, volcanic eruptions, and mountain formation.
Weather is the short-term atmospheric conditions, while climate is the long-term average weather patterns in a region.
Natural resources are categorized as renewable (e.g., solar, wind) and non-renewable (e.g., coal, oil).
Conservation and sustainability are crucial for managing natural resources.

Plant and Animal Cells

Cell theory states that all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.
Plant cells have a rigid cell wall for structure and support, chloroplasts for photosynthesis, and a large central vacuole for storage and turgor pressure.
Animal cells lack a cell wall, have centrioles for cell division, and lysosomes for digestion and waste removal.
Both plant and animal cells have a nucleus, mitochondria, ribosomes, endoplasmic reticulum (ER), and Golgi apparatus.
The nucleus acts as the control center containing DNA, mitochondria produce energy (ATP), ribosomes synthesize proteins, ER synthesizes proteins (rough ER) and lipids (smooth ER), and the Golgi apparatus modifies and packages proteins and lipids.
Key differences between plant and animal cells include the presence of a cell wall and chloroplasts in plant cells, the larger central vacuole in plant cells, and the presence of centrioles in animal cells, absent in plant cells.
